Remind me not to fly on one of your planes.

When people get thrown extra duty because they didn't know something and the boss refused to help.
It's likely they won't bother asking questions the next time they have problems.

Who know's what goes un-fixed.

Fine, I'll do it.

xnihilo,
Code:
i VAR BYTE

i = PORTA            ' Clear mismatch condition
INTCON = %00001000   ' enable porta interrupts on change and clear flag

ON INTERRUPT GOTO in_sig    ' int routine
Remove the other INTCON statement.
