Mark,
Don4t be worried !
It4s very simple to develop complex algorithms
without lose your head.
First of all, you must be used to use indentation.
I use indentation of 3 blank spaces. It4s visually
more confortable do follow a logical sequence with a
good indentation !
Second: Allways

Tottally agree Paul. Always using begin... end makes errors far less common
and your code much more readable. We use 4 space tabs, which both makes
tabbing very obvious and also serves to discourage extremely nested ifs.

Ok
Thanks for all suggestions.
the practice of departmentalising (or encapsulating - to use a less buzzy
word) some of the logic allowed me to move a sub-nest (if..then..else) to a
seperate procedure and to see the logic more clearly.
Neven's case... example looks very neat but *this*
Are you using a message box, or a form of your own that you have made modal?
If the latter, can you free the form and will it then go away?
I have the same problem in an app. It may be necessary to make the form
modal in some other way.

I prefer the Begin and Ends to line up as in (a), it makes it easier to see
a block at a glance, but it is really a personal preference.
Just like using :
for a := 1 to Pred(AnObject.Count) do
Instead of :
for a := 1 to AnObject.Count - 1 do
etc

BTW any preferences for begin end
Personally I find
if blah then begin
DoStuff
end
easier to read.

In a previous language I used, begin...end blocks had an overhead so were
definately not recommended for single statements. I'm not sure about
Pascal/Delphi.

Yeah lets start the old begin end placement debate :-)
I use

unit into its Lib directory.

Design-time only code (e.g. component editors) needs to
be kept in separate units.
These
units will only compile as part of a package: instead of a .dcu, the compiled

It's definately a personal thing, but as I always tend to use compound

I have found this also recently updating a D4 to D6 project and couldn't
figure out where it came from as I hadn't seen this unit before either. It

it must be something new in the of the package units. I just deleted it

wouldn't a scanner (call it via TWAIN?) and a barcode reader (using a
keyboard block) work? 2 pieces of hardware, but the cost of the hardware
should be less than your time to write a barcode recognition system.
I think Gary has done something like this dude, wanna comment?

There is an application called Teleforms (from Cardiff software), that will
read scanned pages etc and convert barcodes or another forms etc into files.
Don't know the URL but a search should find it.

The standard Delphi way (from http://www.econos.de/delphi/cs.html) without
begin/end would look like this
if x=1 then
Say(1)
else if x=2 then
say(2)
else if x=3 then
say(3)

say(4);
which turns out much better than a cascading indent, and avoids looking
Hi Nic,
That would work... But we would like it a bit more stream lined...
Say we have 30 'Jobs', each job has a cover sheet with a bar code on it
and an unknown number of pages that want to be scanned and associated
with that job So the system would scan the first page, see if it had
a bar
