Long shot, but does anyone know what system variable on the
#ZX81 defines if a BASIC program is currently running?
Like, if you want a BASIC program to autorun, you can add a SAVE and GOTO 1, then just run from the SAVE and the running state and current line is saved so it just continues to run after load.
Essentially I want a machine language program to autorun after load and as I'm planning on editing it elsewhere by creating a .p file,no just want to have one USR line and set the program as running from that point.
I'm sure there's a simple answer, but searching isn't turning up anything and the ZX81 manual doesn't make it clear (I tried a few things by poking values in an emulator, but no luck)
