Scancode
A scan code is a two-part or four-part hexadecimal code associated with a keystroke (so called because it comes from scanning the keyboard).
To determine the standardized Business Rules scancodes, run the following program:
10 LET X$ = KSTAT$(1) 20 PRINT UNHEX$(X$) 30 GOTO 10
Each time you press a key, the scancode for that key is displayed.
See the KStat$ internal function for more information.
