delay procedure in assembler

[ohadbp]

hello,

i need to create a delay of 10 seconds in my program.
The delay must use the Timer Interrupt and not in any
other way.

i tryed to make my a new_isr procedure that will "replace"
the original ISR 1CH but i failed to do so.

any ideas how i do that? please help.

thanks in advanced,
ohad.
