QPTR demo Paint.bas

I try to learn a bit more PE programming - and hit a snag.
Demo program PAINT_bas from QPTR runs ok on QEMULATOR QDOS + PE but does not run on QPC SMSQE
On QPC II program starts, interface is displayed. But click on menu does nothing. The program is not frozen and can be stopped by Ctrl - Space.
The compiled version (from QPTR demos) runs both on QEmulator and QPC II
So question is: What generates this strange behaviour?

Vaguely I seem to recall it may have something to do with OUTLN (

Thank you - that was the problem!
paint_bas needs OUTLN also when it's not compiled.
Added line 1115 OUTLN #0 ,512,256,0,0 and now it works.
Still wondering why it was working on QDOS+PE without having OUTLN ...

Hi,
I was rewriting the Paint program, but never got it completed, I wiĺl have a look into what stage I am at.
There is another issue with the QPTR PAINT_BAS program, it uses the variable compiled to detect wether it is compiled. But if Turbo Toolkit is loaded, there is a COMPIKED keyword added to the interpreter, so that fails as well.

Yes, but that was easy to spot, even for me. I changed it to isCompiled as soon as I loaded the program.
Please, can you send me you modified Paint_bas code?

Hi,
Did you rename all the compiled variables?
I have not done much on the updated version, I check it out and get back to you.

HI Andrew,
I looked a my attempts to modify Paint, which looks like what you have already done, I was also trying to add Config Blocks to the code, which was the point I stopped, as I did not know how.
I was reading the documentation.
