The command PRINT USR(30000) will come back with 30000. But I want to surpress the printing. How can I drop the PRINT instruction from the stack? Is there good textbook for MC programming on ZX80? Do you absolutely need to use PRINT ? Couldn't you do RAND USR 30000 ? I see now from your other post ...

You'll find it here on GitHub: https://github.com/sebastienboisvert/ZX81QuickLook.

Enjoy!

So I've recently begun doing some work on a custom implementation for displaying listings of ZX81 programs (a macOS Quick Look plugin, for the curious), and wanted to figure out what the behaviour would be for REM statements that contained some of the control characters (118/newline and 126/number f...
