Editor bug with 465 lines about fastbasic

[dmsc]

Hi, and thanks for the bug report.

Do you have a specific file that produces the error? An ATR image would be great.

I should have mentioned I'm just using this in Altirra emulator atm, haven't tested on real hardware yet so it could be an emulation problem.

I haven't looked into saving code or making ATRs yet, just been writing in notepad++ then copy&paste to Altirra/Fastbasic when I want to test it. It's starting to get tedious now, so will have to look into a better way to develope :)

I don't think it's a copy&paste problem, I narrowed it down to about 450 lines then started adding one line at a time in the editor to see when the problem occurred.

I'll send you the code I have for you to copy over to Altirra so you can see the problem, I assume you can sort out an ATR from there and check on real hardware. (Don't laugh at the code, haven't done anything for over 10 years and nothing on atari for about 25)

btw: github won't let me upload a .atr anyway, here's a .txt file

It was a bad FOR loop while searching for the previous line, the comparison in the FOR loop is signed, so when the address of the buffer wrapped past 32767 the loop did not work.

This is the ATR of the fixed version.

Thanks again for the bug report,

Have Fun!
