clear keyboard buffer in GFA BASIC

Recommended Posts

Hey all, I'm sorry if this has been answered elsewhere but I'm a bit stumped:

 

I'm using a simple inkey$ to jump out of DO LOOP which has the user press the <spacebar> when they are ready to move on and it works nicely, except for the fact I can't find a way to clear the keyboard buffer? If the user has stabbed away the keys earlier on then it whizzes through the stops quick-fast O_0.

 

Back in BBC BASIC it was a *FX command to clear various buffers, including the keyboard, but I can't find a way in GFA? I've tried the CLEAR command, which didn't seem to do what I needed.

 

Any ideas?

From the GFA Basic manual:

 

    LPOKE XBIOS(14,1)+6,0

--> Sets the head and tail pointers to the keyboard buffer to the buffer start,
    effectively erasing the buffer.

or alternately:

    REPEAT
    UNTIL INKEY$=""

--> Deletes the keyboard buffer, character by character.

 

Hope this helps!

That is most excellent; thank you!
