How to go to sleep

[savnik]

I don't know if the

INTCON = $88    ' enable interrupts on RB4 through RB7

is right

[savnik]

some one to help me;

INTCON=$88 looks good to me. You've got the interupts enabled, and Port B change enables also.

Keeping in mind I've not done interupts in PBP (raw assembler yeah) I'd put the button handeling code inside the interupt handler. However, this would be a problem with the BUTTON command as that wants to be inside a loop, so maybe wake up for a while every time you see a keychange.

Maybe this is the my problem and i don't know how to solve.
