Safe Key Getter

Finally, a key getter that is completely protected from ON breaks!
A useful tool for BASIC password protection programs.

Simply run Asm(prgmZSAFEKEY, and the keycode is stored in variable X.
Uses standard getKey codes. See the instruction manual for a table.
If the ON key was pressed, X will contain 101.
The run indicator is disabled.
