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.

Here are a few of the Scan codes:

Key	Scan Code
Tab	09
Shift+Tab	07
Down Arrow	0A
Up Arrow	0B
Left Arrow	0E
Right Arrow	0C
F7	0700
Shift+F7	1100
Alt+Down Arrow	E300
