Hello,
I would like to check for specific key everytime the keyboard is
pressed. In order to do this, my intuition told me that I can
capture the keyboard interrupt vector(int 9), examine the key, and if that
is the key that I want, my program will execute a subroutine.
This problem is, if the key is not what I want, I'll have to pass
execution back to the original keyboard interrupt handler...
Questions :
How do I do that in Pascal? How do I get the instruction pointer to
goto original keyboard interrupt vector and then jump back into my
program? Is there any way I can do it without plunging into massive
assembly language code? I know 8088 assembly language but not much...
Nope, I'm not writing a memory resident program. I'd like to use
this feature in my user interface code where the user can press i.e.
ALT-F in the middle of doing `other' things and `suddenly' a file
directory (or whatever) appear onscreen.
Thanks.
