the general principle is that u make a little routine with say 1 ms delay then 
u repeat that the number of times u need to get the desired longer delay.
Depending on if u need the pic to perform other tasks while in the 
delay-routine u must count in the time it takes for it to do that so the delay 
is accurate, this can be very tricky and should be avoided if possible.

Also, u could use a IRQ routine but that usually insn't on the beginners 
first-to-do list.

I haven't used the '84 so i am not sure if it has a PWM output, that should
be possible to use for servocontroll ???
