fastbasic is awesome, i wish they had it in 1984 for compute! magazine.

 

my Automated Doily-Handkerchief Designer (adhd.xex) program runs about 5.5x faster.

But the xex from CTRL+W has an extra character at the top left...

...while within the IDE it is fine...

Maybe it is my mistake?  Or the emulator atari800?

 

Thank you

 

edit: this is 4.3 so could be fixed already,

It looked like the XEX was converted from ATASCII to ASCII when you extracted the XEX from the ATR after the CTRL-W, because the extra char is ASCII 10 ($0A=line feed), and it should be ATASCII 155 ($9B), which it must be printed after clearing screen as there is no semicolon at the end of the "?chr$(125)" statement.

 

To verify that, I put your program in FastBasic 4.3 and created an XEX, then I binary-compared both XEX and I found that all ATASCII 155 where converted to ATASCII 10 (11 occurrences) and also few other bytes. The attached XEX is the uncorrupted one.

 

What surprises me is that your XEX works after such heavy corruption!!!

 

BTW, try the PAUSE statement to replace the empty FOR-NEXT loop.

As Vitoco said, the problem was that you converted the XEX from ATASCII to ASCII, and somehow it still works!

 

Mi suspicion is that you loaded the program in Atari800 from your system using "H6:ADHD.BAS", the emulator "H6:" device converts ASCII/ATASCII on the fly, compiled and saved it to the same "H6:". To save the binary you must use "H1:ADHD.XEX", the "H1:" device is the same as "H6:" but without the ASCII/ATASCII conversion.

I recommend you to use the latest beta version, so you can use the BREAK key to return to the IDE and also you help by finding bugs in that version 😛 , download it from here: 

 

 

Have Fun!

of course you guys are both right, i suspected it might be a PEBKAC :)

 

thanks @vitoco for the pause tip... i even read the manual but it went over my head to use it for this.

 

thanks @dmsc i will get the new beta
