Keyboard input/Keypress check is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
Determine if a key has been pressed and store this in a variable. If no key has been pressed, the program should continue without waiting.
BASIC
ZX Spectrum BASIC
10 REM k$ will be empty, if no key has been pressed 20 LET k$ = INKEY$
PureBasic
Returns a character string if a key is pressed during the call of Inkey(). It doesn't interrupt (halt) the program flow.
If special keys (non-ASCII) have to be handled, RawKey() should be called after Inkey(). <lang PureBasic>k$ = Inkey()</lang>
