does it make any differnence if you remove the first five lines?
i also can see no reason for setting variables afterwards.

i would try to remove the first 5 lines, because they do not affect the rest

Have you either SHELL or CALL ABSOLUTE? 3. don't forget to set the lines PUSH BP - MOV BP, SP at the b...

Can anyone tell me how to install an interrupt routine?
It should be executed 10000 times per second. I know
how to include asm into my source, but i want to
execute it in the background.

I hope somebody can help me with my problem.
