Hi Greg
this is not a real "inkey" function like in BASIC.
The BASIC inkey$ function reads the keyboard "on the fly" and does not wait for a key to be pressed. But this mc stays inside a loop (and does not return) if no key is pressed:

Code: Select all

@Again
	Call Keyboard	;Call ROM scan keybd.
	INC L		;Check for no key press, L=FF
	JR Z Again	;If L=0 then Scan again.

A new "INKEY$" that fixes the problem with pressing Space/Break has to be a MC that does not return to Basic. Because if it returns to Basic, Space will break at any Basic statement.
