Re: [Ql-Users] Stupid AND

[Wolf via Ql-Users]

Hi,



FALSE AND ERROR is FALSE ? That cannot be !


I disagree.

FALSE AND ... whatever  is FALSE since whatever is never evaluated.


FALSE AND ERROR has to be ERROR !!!


Definitely not.




The first condition (a<>0) is NOT met and so, in any other programming
language I use, the second condition isn't even tested, as the result
will be "false" anyway because of this.


So you will ever get big BIG ERRORs...



I'm not sure I understand. The above example makes sure that the error 
doesn't even happen which is the whole reason to write it like that.



SBASIC is better ;-))


In this instance, not to my mind. :-(

Because there is no order for evaluating the first and the second condition in 
the AND operation,
In any way both have to be without any errors.

FALSE AND ERROR is FALSE ? That cannot be !

My systems use 7.65 without problems, which was the first high colour
version. 7.66 has at least the extension problems that I noticed, too.
I'm not up-to-date what changed in v8.

I'll try to get the sources (and manual), maybe we can address some of
the problems.

No, this was the last mode 4 version.
v7.65 is the first attempt at GD2 compatibility.
IN v8.xx the Long Words that hold the palette parameter in the low bytes,  
also use the high bytes for extra options like timeout.
This should not be a problem when used from S*Basic but may be an issue  
when called from machine code when the high bytes are taken for granted.

This could be why in QDT LSEL does not work properly.

Yes, v7.66 is buggy, but v8 is not much better...

In my experience, the only valid QMenu version is 7.64. v8.00 got several
annoyances and compatibility issues and, IIRC (that was many years ago),
removed things from its configuration that broke the way I always used
QMenu, so I rejected it years ago, and religiously (for an atheist,
that's quite a superlative !) kept v7.64 on all my systems.

Re: [Ql-Users] QMenu v8

[Giorgio Garabello via Ql-Users]

yes, but probably is a QDT problem..
QMenu 7.66 has a lot of problem, ink  color in view_file remains always
black, extension filter don't work and some other problems... Qmenu 8,
works well..
maybe in QDT the author has done some "tricks" .
Probably the author had to make some adjustments to make it work, which
pggi annoy version 8.

Re: [Ql-Users] Qbase

[Daniel Baum via Ql-Users]

Hi all,

That's very good news about QMenu.

Anyway, two people have sent me the correct parameters for FILE_SELECT, and
I am coming to the conclusion that version 7.66 ignores the file extension
and always shows all files in a directory. The same is not true of a
version 5 that I also have.

The command that I used is something like
a$=FILE_SELECT$("Open","QBase","win1_qbsrc_","_dbs").
Everything is set up correctly in the dialogue box but there is no
filtering.

I have tried this on QPC2 and Q-Emulator, with no other extensions loaded,
to eliminated some sort of clash.
