A89: detecting the ON key
In my program I use the following code to check whether the user pressed the
ON key:
int key;
if(!OSdequeue(&key, kbd_queue()) && key == KEY_ON)
retreat = TRUE;
If the user pressed ON during the evaluation, I want the program to return
certain string (the partial answer). However, if I press the ON key, the
program returns "Error: Break", pretty much what would have happened in a
BASIC program. Is there a way to intercept the error message and return what
*I* want?
Thank you,
Sincerely,
Alex Astashyn
