Sorry Al, maybe a dumb question here, but will I need to see these "include" files to understand things fully, just asking in the hopes that is the answer is yes you can attach them so when I get home i will better be able to look at things.

INCLUDE "DT_INTS-14.bas" ; Base Interrupt System
INCLUDE "ReEnterPBP.bas" ; Include if using PBP interrupts

thanks again!
