Can anyone tell me what combination of peeks will tell me how much memory I have left while writing a Basic program? I believe it would be STKBOT - E_LINE

Code: Select all

PRINT ((PEEK(16410)*256) + PEEK(16411)) - ((PEEK(16404)*256) + PEEK(16405))

but am not sure.

It should be ERR_SP-STK_END-machine_stack.
Maybe calculate 100 Byte for machine stack to be on the safe site.
