Re: New ZX81 Games
Cubimaze works as expedted and does not crash ... But GOL starts and creates a blanc inverted screen in 2 steps? First leaving corners, Yes the clear corners? NO If so then game loads ok. And then pressing a key (latest version NEWLINE/SPACE) gives the cursor? And THEN setting a colony with Z gives...

Re: "Inline" BASIC Extensions
using 21 LPRINT C$(1 to 2); is easier. Then the machine code can fetch PRINTABLE(!) characters from printer buffer (address 16444....) and the length of the basic code does not need to be calculated to call the machine code (line 20). A single number X can be passed to m/c using RAND X and fetch th...

Re: "Inline" BASIC Extensions
Hi Greg nice demos :) Maybe the subroutine's interface to the machine code can be done more easily using LPRINT ; if printable characters need to be passed to m/c. Instead of poking the characters into the machine code: 21 POKE L+1, CODE C$(1) 22 POKE L+3, CODE C$(2) using 21 LPRINT C$(1 to 2); is e...

Re: IF I would write a book about coding a 1K ZX81.....
What style of writing would you like? For instance I could write it as telling my story or just like a manual explain how to get most out of 1K Maybe the structure could be like the ZX81 BASIC Manual? It is well done to learn BASIC. And to learn C, the same structure was used: https://forum.tlienha...
