GetKey

Library: #include <keys.bas>

Returns the Key Scan code of the key pressed or 0 if no keypress is detected.

Syntax

GetKeyScanCode()

Examines the keyboard and returns 0 if no key is pressed (Unlike GetKey, it does not way for a key press).

If there is at least a key pressed, returns all of them ORed (bitwise).

Examples

#include <keys.bas>

PRINT "PRESS H, L or both"
DO
LOOP UNTIL GetKeyScanCode()
PAUSE 10
x = GetKeyScanCode()

IF x = KEYH THEN PRINT "You pressed the H key"
IF x = KEYL THEN PRINT "You pressed the L key"
IF x = KEYL bOR KEYH THEN PRINT "You pressed both"

To detect more than one key, they must be in the same "row half" (see keys.bas library) for further explanation.
