making transparent pdf output

[Dr. Hawkins via use-livecode]

I’m finally getting back to work on this project.  

The first thing I need to do is figure out how to make livecode pdf output 
transparent.

A page of one will be mostly fields with transparent backgrounds.  But when I 
pint to pdf, the background of the card, supposedly transparent, renders as 
grey when merged on top of another pdf (much as a card with no background 
color).

Is there a way to make livecode produce a pdf with a transparent background?

Or failing that, a way to edit its pdf output to make its background 
transparent?

I’m *trying* to find a forum for working with raw pdf, but the noise is so 
heavy from all the pdf software that I can’t find anything..   I’m stuck 
working from the adobe reference document at the moment, which is kind of like 
trying multivariate calculus without understanding algebra . . .

Re: Using MySQL on (headless) Linux

[Dr. Hawkins via use-livecode]

That the deployment needs to be headless doesn’t prevent you from running it n 
the IDE to gain access to single stepping, breakpoints, and the like.

I don’t remember why offhand, but before finding the -ui option, I did some 
experimenting and fount that I could get the linux version of 5.something to 
begin execution.  It ran at least preOpenStack before attempting to start the X

I once wrote a program that compiled without error and executed on the very 
first try.

And, umm, the university would not have approved of what I consumed before I 
went to the computer lab . . .

It used random numbers to see how many landed in the circle, allowing it to 
compute pi as 3.2 . . .

No less intuitive than there being fundamental technical reasons that it was 
necessary to sacrifice small animals to SCSI chains, which I accepted long ago 
:)

The result is curious . . . the outputted pdf is now *entirely* grey, yet when 
merged through PyPDF2, a single renege field appears from within the grey (the 
only field the I hadn’t set to not be opaque, I think.  Or perhaps it’s the 
only one with a white rather than empty background.

Still, though, the grey of the livecode file blocks the pdf beneath it.

I’m printing each LC page with 

set the backgroundColor of otCd to empty

set the opaque of group "oGrp" to true

set the blendlevel of group "oGrp" to 100

set the blendlevel of otCd to 100


print otCd from otTl to otBr into 18,18,576+18,756


(where otCd is the card with my LC fields, all contained within group ogre). 
(otto and otBr hold the top left and bottom right of group ogre)


Just what are you suggesting should get a blend level?

Or would it make sense ()or be necessary)if I just printed each  field into its 
own coordinate?

And a bit of further testing shows that the field that appears after merging is 
actually a region which contains two fields and the space between them,  and is 
apparently shown the background pdf in this limited area (but not the contents 
of these fields.

Now my head is spinning . . .  anything more  you can tell me beyond what the 
dictionary says would help, as my head is spinning . . .

The card and the stack also are set to empty backgroundcolor

I’ve also set the opaque of stack, card, and group to false.

I’ve even checked the effective opaque of the selectedObject,  which is false 
for the group I print it’s pieces.

Yet I get a grey overlay when the pdf is merged into another pdf.

I’m within spitting distance on this merging of pdfs, using livecode to 
generate python code and using the PyPDF2 library.

My last problem is that the pdf generated by livecode creates a great 
background, whereas it should be transparent.

set the backgroundColor of otCd to empty

print otCd from otTl to otBr into 18,18,576+18,756

gives me a grey background that obscures the form I’m placing my output on top

cr, lf, and reading in terminals/vim

[Dr. Hawkins via use-livecode]

I’ve tried every combination of cr, lf, and crlf, but whenever I assemble into 
a file, I get something that neither the OSX terminal or vim recognizes as 
having lf in it

I build a set of commands in mrgCmds, appending cr as I go, but I get a bunch 
of ^M in the otherwise uninterrupted stream with vi and less, while cat shows 
me the last line (presumably, as it keeps writing it over.

The code in question is

put "outFil=open(theOutPdf, 'wb')" & cr after mrgCmds

put "outFil.write(theOutPdf)" & cr after mrgCmds

put "quit" & cr after mrgCmds

replace cr with crlf in mrgCmds

open file fldr & "/theCmds.py" for write

write mrgCmds to file fldr & "/theCmds.py"

close file fldr & "/theCmds.py"


please, someone help, before the termcap flashbacks tern me into a quivering 
blob of fear!

making outputted pdf background transparent [ was:high resolution when printing to pdf, ...]

[Dr. Hawkins via use-livecode]

I’ve managed to make overlay of pdfs work with PyPDF2.

Now I have the problem that livecode outputs a background color to the pdfs I 
make.

Even if I et the background color of my card, the groups, etc. to empty, I 
still get a grey background, instead of a transparency.

This means that when I overlay them, the supposedly transparent background 
overwrites everything else :(

This is another showstopper.

Is there a way to control this?

Among other things, it means that a watermark can’t be made . . .

What I did was basically translate largely from postscript.  With postscript, I 
could name the donor 
file’s commands, and then refuse sections of the donor (in some cases, 
repeatedly, possibly once,
possibly dozens of times ).

As I think about it, I don’t think I’ve ever said *anything* nice about pdf.  
I’ve generally called it a bastardization 
of postscript, but in this case, “castration” might be a better word . . . (but 
then, when talking about cars,
I refer to the period from the early 70s to the mid 90s as “the Great 
Emasculation” . . .)

high resolution when printing to pdf, either from images or pdf widgets

[Dr. Hawkins via use-livecode]

I’ve seen references, even in the bug report, to “directly” printing to pdf 
from a widget.

My experience has been that it still reduces the pdf to screen resolution.   

I still insist they the fact that the engine *renders* the pdf, rather than 
including it, is a hard-core bug.  I attached an example of including parts of 
a pdf into another.

In the meantime, though, has anyone actually managed to get hi-res output of 
either a pdf, jpg, or png into an outputted pdf?

The only way I’m seeing at the moment would be a bizarre process in which the 
stack is duplicated at 400%, and a script looping through to expand and replace 
every field, reposition and change the text size, etc., and then open the 
33”x44” file in preview (or whatever) and export from there as 8.5”x1” . . . 

This will yield crummy results, though, as livecode’s posting of text and use 
of margins in fields is nonlinear (to put it charitably!)

*IF* I could export to pdf at object density, I’d temporarily use png extracted 
from the pdf with an external program.

Another potential solution would be to export without the pdf and build a 
script to an external unix utility that could print a page of source pdf and my 
output to a third file.

And if I could fully figure out the pdf file structure, I could expand my 
example file to write a custom pdf merging the field output with other pdfs . .

The catch is that I’m doing this to *build* those queries (or, actually, to 
invoke a combination)!

the combination I mentioned would cause another value to be calculated with 
that formula if either pay or monthly pay changed.  That is, in the routine to 
update monthlypay (or pay), another handler would update this dependency

Currently I have a big ugly switch for each variable holding database commands 
(or usually  functions calling them) to update dependent variables.

The main table for a given debtor (client) has a few hundred lines and a half 
dozen columns (for string or pennies, default values for each, and a couple 
more).   The other table has anywhere from a couple to a couple of hundred 
entries with several dozen columns.

Combining debtors in a single table would be undesirable for a variety of 
reasons.

Doing that procedurally brings me back to the same column, while manually 
entering like that is just asking for trouble—there are *so* may entries that 
I’m going to leave out a space, and *BAM*.

A shortened version of what I have is to create theTrWds
repeat for each trueword theVar in varForm

switch

case theVar is among the keys of theTrWds

case theVar is a number

case char 1 of theVar is not an alphanumeric character —but I need a valid test 
for this

next repeat

break

case theVar is among the keys of dinfoDtyps

put theVar & space after theTrWds

break

end switch

end repeat


repeat while word 1 of theTrWds is not empty

put word 1 of theTrWds into theVar

delete word 1 of theTrWds

switch

case theTrWds contains theVar

--it's a substring of another; skip for now

put theVar & space after theTrWds

next repeat

break

default

put replaceText(varForm,theVar,"getVal(theVar,,,dbtr)") into varForm

break

end switch

end repeat

replacing only exact matches in script

[Dr. Hawkins via use-livecode]

I’m finally writing my new version of dependency calculation for database 
variables, with a supposedly clever easy format fo entry and machine calculated 
script.

I need to replace only exact true words, though.   So I need to be able to take 
an input string such as 

5*pay - 2*monthlypay

and be able to replace “pay" with

getVal(pay,,,debtor)

without  replacing monthlypay.

I can’t with any certainty control the order that variables will appear in my 
”raw” formulae (too many ways to blow up!).

I’ve considered requiring a space before and after, but, again, two many ways 
to blow up.

I could manually parse the line, looking for starts and stops, but it’s both 
ugly and asking for obscure bugs.

I could make a list of all the truewords, and cycle through, moving any one 
that is a substring of any other to the end, and repeatedly looping until the 
list is empty.  Ugly, but the least insane of the options I’ve come up with.

I can handle a performance penalty, as this routine would run only in the 
development version, with the resultant array saved as a stack property in any 
shipped version. But I’d still like it to be as fast as I can and avoid 
thumb-twiddling . . .

No wisecracks from me—I ran Word 4.0 and 5.1 on the same computer for years.  
It was the rare case where msft didn’t damage a file when opened with an older

Also, to say something on topic . . . note that OSX is kind of ham-handed on

I have never seen this before, and the stacks (and routine) involved are a few 
years old!

The procedure dhDevBldFlds loops through my source stacks and finds controls 
that need to be handled for output, and sets appropriate attributes.

All of a sudden, it’s bombing with 

Message execution error:

Error description: Stack: stack is password protected

Hint:

It has processed *several* cards by the time it hits the control where it does 
this (I set a property of my main stack with the control being processed.)


While the stack does have a password, it has long been unlocked by the time 
this is done.

import from multi-page png, and automating pdf-> png

1) is there a straightforward way to batch convert pdf to png of specified 
density?
2) for a multipage png, is there a “decent” way to use import to get a chunk of 
a specified page, or do I need to know the pixel height of the page and do the 
math?

I’ve just uploaded some files with the core of a solution.

Having never gone inside a pdf before today, i converted some a pair of simple 
postscript files and converted to pdf,  a 3/4 circle to play the role of the 
raw source pdf, and a box to play the role of whatever other control.

I then edit the circle’s file as overlay.1.pdf ( the entire resultant file is 
in plaintext), defined a clipping path that doesn’t include all of it 
(representing the region of pdf actually displayed by the widget), and then 
added in the stream of the box.

The trick here is to, rather than drawing the widget, just pass the raw source 
of the donor pdf into the new one; no need to render at *any* resolution.

Printing to pdf already deviates from the printer by passing the text to print 
rather than a rendering of it; this is just the way to pass the pdf. (OK, I 
haven’t tried regular printing since 5.0; maybe something changed).

I’m to even having success doing it that way. 


 I gave up on printing itself back with 5, when even fonts only rendered at 
screen resolution . . . I think that’s changed since then, but I”ve been 
exporting to pdf since then.  (besides, it’s pdfs that we use to file in 
bankruptcy, anyway).

It was I that filed that bug .  .  . but I haven’t succeeded in exporting 
around it yet.  I have three uploaded files for comparison — iMac, retina 
MacBook, and scaleFactor 4 on the iMac.

It’s been a couple of decades since I played with postscript (and, much as they 
deny it, it *IS TOO* Forth!), so I don’t remember details.

My thinking, though, would be to use the postscript base of pdf and skip 
rendering entirely during export.  Instead, include the source pdf file in the 
output, and specify a region to contain "250,220 to 400,550 of page 4 of 
mydoc.pdf”

In my case, just resizing the pdf for resolution won’t get me very far—I will 
have several regions of pdfs included in an output  page, possibly but not 
always from the same page of the source, *and* a bunch of livecode fields.  
I’ve considered cloning the card and resizing every item, but livecode’s (and 
the fonts?) handling of margins and the like seems quite non-linear, so I 
wouldn’t get my carefully arranged output where I’ve meticulously placed and 
adjusted fields.

Other approaches I’ve contemplated:
1) turning the pdfs to quad density png or pg, and letting my developer 
maintenance machine scan my output cards pieces, stick make a graphic 
corresponding to each pdf, put that in the layer immediately above the pdf, and 
turn it invisible except when exporting.  (but relayerGroupedControls is kind 
of touchy . . .)
2) export to a pdf without any of the source pdfs (just my own fields), and 
write a build file with source pdf name, page, and region for each element, and 
run a shell script to build a postscript file using postscript versions of my 
source, and then turn that back to pdf.

math on widths doesn't add up

Playing around with a couple of things needing alignment, I’ve noticed that the

For example, I have a boundary rect of width 12, with a left of 0 and a right 
of 12.

One of these is wrong . . . a width of 12 would go from 0 to 11; 0 to 12 is 13 
pixels wide . . .

It seems that “right” actually means, “the pixel to the right of” . . .

When the project opens,  routines run, bumping versions for a new day.

And when that happens, it goes through every field and sets the textHeight
to the custom txtHgt.

textHeight is set for the source, but when it's group copies over, this
property is lost.

textHeight changing again when copying fields from one stack to another

[Dr. Hawkins via use-livecode]

I licked this a few years ago, but forget how.

I have fields being copied from one stack to another (actually, the group
is copied) for output purposes.

the sharedText and lockText are both set to true, and maintenance routines
cause the textHeight to be set to my custom property txtHgt.

I'm seeing fields change from a set textHeight of 12 to default/italic
displayed 11 on the new cards.

Could someone kindly remind me how to deal with this?

losing font info in fields again

[Dr. Hawkins via use-livecode]

I think I ask this every couple of years (and it would be more often, but I
sometimes find the answer in my archives).

As my program copies groups from one stack to another, I am losing field
formatting information.

This time, the offending fields have, iirc, both ArialMt and dingbat text,
probably both in different heights.

It appears that upon copy, I have a font with serifs, and the size changes.

The sharedText of the field is set to true.

I vaguely recall that the reis a field property that isn't in the inspector
that needs to be set, but I'm baffled at the moment :(

Yeah, but if you're doing any level of *serious* matrix multiplication,
there's no substitute for Fortran: it's a basic feature of the language.
You can approach the speed by optimizing C, but you're putting in work for
what could come from "C=MATMUL(A,B)" (and you're not limited to
one-dimensional arrays, either).

I went into LibreOffice (where it won't paste this character from the pdf)

I pasted this in one, and it does seem to be windings, size 12.

I then found an error in my maintenance routines:  it checked for the text
font of the last char being "Windings", rather than "Wingdings" in a
case-sensitive section.

So then I set a script to loop through every field n the stack, and when it
found offset("",the text of tgTg) >0, it sets the textFont to windings and
the textSize to 12.

I'm not sure I have the same character, but it sure looks right.

And something funny is definitely going on . . .

Thanks so much; thus aspect of my forms *finally* looks right after a

They also work with postgreSQL.

This was a major factor in my switching.

I think mySQL now has rollback, but it didn't have fun rollback at the
time, either.

Overall, postgres is the more mature/stable of the two, but it doesn't come

hmm, for spaces, that seems to be correct.

But that just proves the point; spaces in filenames are evil :)

I learned unix on a cluster PDP-11 over three decades ago, and I'm still
off on this.

There are other things, however, notably environmental variables, that do
not get escaped in the weak quoting of double quotes.

You can change them.   once you have the name in filNam,

put filNam into newFilNam

replace space with "\ " in filNam

replace space with "_" in newFilNam

get shell ("mv filNam newFilNam")


or, just use newFilNam--but spaces in filenames are always going to hurt
and cause problem, not mater the source.

double quotes cause evaluation (for shell variables?), back quote (`)
causes contents to execute.  You seem to be using ', which is a literal.

Oh, I see.

You have *SPACES* in file names.

This *ALWAYS* leads to suffering.

Quoting a filename does not make it ok; it's still multiple words. If you
want to keep such evil names, you'll have to escape those spaces with \
 (backslash).

A better idea is to get all the spaces out of filenames.  I only allow
letters, dot, and underscore.

You also have hyphens, which have meaning on some operating systems.

There's nothing like the joy of going weeks of carting the water from the
kitchen sink down the hall, as it drains into a five gallon bucket, because
the sewer line is 100% blocked a couple of feet under the concrete slab
under the the living room.

Not even the thrill of the redneck connection of a garden hose to the
washing machine to run down the driveway, or even the 2'x22' trench three
feet deep across the room that you get to step over for a couple of days
 as the work is done and you wait for inspectors.

On the bright side, we replaced with ABS rather than cast iron, so it
should last a touch longer, and even the same 50 years means i wont be here
when it happens . . .

You may (or may not; it was years ago) need to enclose the command  in

need to redirect output.

 so

shell ( "(domycommand > myoutput &)"  )

How about something similar to the unix convention of  indicating the shell
to use in the first line of a text executable (e.g., #!/bin/tcsh ) as a
comment?

so the first line starting with, perhaps, "--#" would indicate that  what
follows is an expression which evaluates to a button or other stack that is
to be the behavior of the stack?

I found no coherent relationship between the location on my iMac screen and
what livecode reported once I changed  the scaleFactor of the stack.  With
each 10% increase, the stack seems to move (usually) right, and also up or
down, possibly causing the menubar to be above the screen.

I also see an intermittent issue that livecode things the mouse pointer is
about an inch higher on the screen than it is, but the horizontal seems
correct.  This also seems be be limited to browse rather than select mode.

I think that is the error here--it shouldn't be possible to delete the
stack containing a target while that target's script is running.

For my transient stacks, it's

send ("delete stack " & the short name of this stack) to stack "mcp" in 0



(where "mcp" is the main stack with routines, etc.)

Not when I was trying a couple of years ago.

I tried both with and without including the BEGIN/END, which gets

the archives from it (err, do we keep those?  google my email,
livecode, and mySQL to get a start on one of the parasitic sites).

Unless something has changed, you can't submit multiple mySQL commands
at once from LiveCode, whether you immediately execute them or not.
If the server is not local, you may find 2000 consecutive latencies to
be brutally long (as in minutes, not seconds)

You can, however, with postgreSQL and SQLite.  In fact, it's a couple
of insertions  done as a singe transaction with SQLite every time I
open a client, and a similar one to the posts server when I create a
new one.

mumbling towards a crash cause

I *may* have just had an insight on a cause of IDE crashes.

A moment after I changed a custom property, and before the stack was

Or, it could be coincidence, but this may be consistent with some of
met other crashes.

Re: advertising,again, and is anyone actually making money from it?

[Dr. Hawkins via use-livecode]

I guess I make it three.

I signed up, and didn't log in, the day they announced their own
email, just to stop someone else from being labeled dochawk.

Then at my reunion a couple of months ago, it came up that someone had
a page for our class.  We went through a comedy of errors trying to
find and login to my account.  Or maybe that I could  login, but that
my name didn't show (as I'd never given it more than initials).

Somehow, we connected one of them to my wife, and I guess that let me
see a name and send a message, or maybe they sent her some kind of
invitation.

And then they were exasperated that I hadn't filled out a "profile" or
some such.

I logged in for a while, wondering if anything interesting would
happen.  I found that adblock could make a couple of particularly
annoying columns it through at me go away, but really did not get
interested in the blather.

And then, once you don't log in often enough, it sends you messages
offering to help . . .

I go back to 1984 on usenet, but just don't understand this whole

advertising,again, and is anyone actually making money from it?

[Dr. Hawkins via use-livecode]

I've tried to get this discussion going before, and failed.  So
perhaps a crasser start:

Is anyone actually making money from  livecode app's advertising,
either iOS or android?

If so, how did you get it done, who did you use, etc.?

All I have so far is that the folks that livecode supposedly set up
have no interest in dealing with us until we have sufficient volume to
interest them.

I *thought* that that was in there somewhere, but I didn't see it when

Yes, that did it.  I had the item del, but had used "ascending" in the

crumbly IDE

[Dr. Hawkins via use-livecode]

This is in the 8.2 series, but I think folks have sen it before.

I haven't nailed it down yet, but I seem to permanently lose parts of
the IDE, possibly after toggling messages off and back on from the
toolbar.

The message box still works, and can close stacks, but the stats seem
to completely ignore messages forevermore.

About 5 times today, I think . . .

sorting with number late in name

[Dr. Hawkins via use-livecode]

Now that I've hit ten numbered items, I'm having an issue with
maintenance routines.

If I have the items

  p13_1.07
  p13_1.08
  p13_2.04
  p13_10.01

I want them to sort in that order.  However, the 10 will sort between
the 1s and 2s.

Is there a "decent" way to do this without a custom function?

All I'm coming up with so far is a script that looks for a single
digit number and renames to put a 0 in front of it . . .

Was this to me?

I don't create alerts, but there's the occasional dialog box.

Haven't looked to see which process has gone nuts; it's just that
sometimes things go non responsive and/or
the message box cannot be brought up.  I think the rest of the menu is
active but does nothing when this happens,
but it hasn't bitten me enough to make sure.

Overnight doesn't seem to make a difference for me.  This seems to

You're a bit over my head, but . . .

wouldn't that left join bring *all* the entries for table2 and their
numbers in, so that I would still get repeated animals?

Should there be a . in the middle of the last word?

In test,

Select debtor_table uniqDna, debtor_table cname from  (select
distinct cname FROM debtor_table as mytable2) left join debtor_table
ON debtor_table.cname = mytable2.cname ;

and I get,

(in fact, I need cname||cadr, not just name, as some creditors end up

results of SPLIT when keys not unique

[Dr. Hawkins via use-livecode]

If I use split such that keys are not unique, will that have the
effect of filtering out duplicates?

For example, if I have
  dog 3
  dog 5
  cat 8

and SPLIT it, will I end up with 5 in entry dog?

More specifically, is this a defined behavior, or "just how it currently works"

I'm trying to find a quick & clean way around SQLite's lack of
"DISTINCT ON"--I need to keep those numbered keys attached to work
with, and DISTINCT alone won't due that.

system user dialog data colliding

[Dr. Hawkins via use-livecode]

I finally found the source of this oddness after a couple of years . . .

On startup in development environment, there is a check that updates the
main stack if it is not from today, using "save as".  The name is to the
effect of "mcp.171004a.livecode"

This invariably triggers a live code message asking what to do with the old
stack (and sometimes a flurry  alternating between the old and new stack as
I save each).

There is also a custom dialog that automatically loads and asks for the
database table to open (with client names, not raw table names).

The second of these to launch blocks the first.  The result is that I have
to hit "cancel" on my own dialog, but execution remains stopped until I
deal with the system message.  In turn, that means that the dialogData
becomes "save" rather than the "cancel" associated with my own dialog.

It never occurred to me that the system portion would be using this
property.  (To add insult to injury, I changed from setting a custom
property in my dialog to using dialogData).

I suppose that since the IDE tries to be written in live code as much as
possible this may not be a bu, but it is certainly unexpected . . .

"cleanser" for SQLite and UTF

[Dr. Hawkins via use-livecode]

I've really never paid much attention to UTF; 7 bit ASCII is fine for
everything I've ever needed to do (save immigration forms, but that was
handled by someone else's software).

Is there a "cleanser" hidden somewhere in livecode that converts arbitrary
text to plain old boring (and those SQLite-able) text? ("UTF" itself yields
no dictionary hits . . .)

attaching my group id to a control in a subgroup

[Dr. Hawkins via use-livecode]

I have a uniqDna value for each datum in my data.  This is used to store
and retrieve it from a database.

When I create an output group for one of these (and there are a great many
different output groups), the group is labeled with these IDs.

The output group will typically contain label fields and graphics, but gets
its unDna set to the corresponding uniqDna.  It also contains fields for
output.

When an output field is modified, the handler calls the seal routine,
passing the field name, new value, and the unDna.

I had made, for performance reasons, the strong assumption that the output
fields would always be a top level member of the output group.  I also
designed output groups which, for organizational reasons, group the output
fields . . . oops . . .

The closeField handler follows the rule, and assumes that the unDna of the
owner of the target is the uniqDna value it needs.  This backfires when not
true :(

One obvious solution would be to simply ungroup the offending groups--but
there are good reasons to want it have subgroups (such as sharing subgroups
for maintenance of similar outputs with shared elements).

At the moment, the three possibilities I see are,
1) recurse upwards until a group with a unDna is found (well, close; there
are universal fields with no unDna)
2) check the owner of the owner of the target
3) redundantly set the uDna of every output field at group creation/copying
time.

I need this to be blindingly fast, too (although I doubt that this is a
problem in 2017).

Am I missing an obvious way to do this?

Oooh, yes; automagical maintenance would be wonderful!  (really? my

And to be clear, I am *NOT* suggesting in any way that Livecode get a GOTO;
I was suggesting that there are *very* rare cases where they are useful.
 (I can probably count the number I have *ever* used on my fingers,
possibly of one hand [unless you count the ones driven by performance and
how memory was accessed in interpreters, but that still gave you two per
program {jump to high/slow area for onetime setup, then to mid-memory main
loop above time critical subroutines, and possibly a third from the end of
the main loop to the beginning if the language couldn't loop forever}]).

(and as dust drifts about the cobwebs of my memory, I think that on what I
think of as "my goto" was used instead of putting the common section into
another routine to avoid the computational cost of that context switch;
this was in the recursive core routine that was called zillions of times in
the program which ran for a couple of days [initially more than that].   If
you need that kind of optimization/performance, livecode will be fairly low
on your list of choices . . .)

Word processor, spreadsheet, browser, email, and a few games probably
covers 99% of users.

On a phone, many want their facetwit applications, too.

My interest in a smart phone ends at navigation, camera, and caller ID.
Oh, and enough voice control to place calls.

I'd be tempted to switch to an android (I actually had the original

Security and privacy *are* what I'm buying when I pay extra for an iOS
