USART interrpt in PIC16F877A

Hi,
in the help of my compiler is written that "on intterupt goto label" instruction,
add an instruction to check after each instruction to find that interrupt is happened or not and then it goes to interrupt routine.
for example in "pause" instruction ,if you want to make 200ms dely ,you should act like this:
for i=1 to 200
pause 1
next i

instead of pause 200
that program help to go to interrupt routune faster because after any pause
it check the interrupt but when you use pause 200,after 200ms it goes to interrupt routine.
this is my compiler problem.
maby my problem is like this.
