Reading, storing and writing screen values

[boriel]

Thanks; I'm not good with ASM so I have to find some routines to reuse them. About look-up tables, I've found this: chuntey.wordpress.com/category/z80-assembly/ ...But the code doesn't work in zxbasic. Anyway, I'll continue to mess with this

Cheers

Hey, Interesting. Maybe we (you included) can port it!
I'm currently really busy, but will help in any question regarding to syntax, toolkit capabilities, etc...
