I've almost finished the IS-BASIC versión but the execution is tremendously slow.

You can try to compile with Zzzip. (http://enterprise.iko.hu/books/Zzzzip_Compiler.pdf) (But it has a few limitations.)

Yes, I know it, but taking profit of the structured basic capabilities I filled all the procedures with local variables. This is something that needs to be changed with Zzzip. Once the basic code is finished I'l try to change all this stuff in order to zzzip can compile the code.

Thanks

Zzzip may compile programs with local variables too. It doesn't always cause problems, I think. You can try it.

If I not mistaken, Zzzzip doesn't like same names of local and global variables.

Yes, I've to rename all the local variables coincident in name. Not a big work but I let it until finished.

Thanks

As I told before, here is basic version of the program . It is extremely slow. I checked it in the emulator using the full speed option.

I had several comments in source using the character ! and almost finishing the code gave me always a runtime error "Insuficient memory". That took me crazy. Once removed the comments everything is ok. Maybe a bug in the basic or the vi editor writing some extrange character with the !

Anyway here it is

[attachmini=1]
[attachmini=2]

you could try to keep everything in one page with PRINT AT, i think it would save also memory.

Just a dozen of comments made the execution crash. I cleaned all and works. Maybe the vi editor under Macos (I used it) inserted something abnormal for the basic interpreter.
