Hi Dave- As you requested, here are the 2 files:



This is the source file config statements (at present commented out)
'--------------------------- Set Processor options. THIS IS MPASM -----------------------
'ASM
' CONFIG OSCS=OFF, OSC=HS
' ; Oscillator switchover disabled, HS Osc enabled
' CONFIG BOR=ON, PWRT=ON, BORV=27
' ; BOR on, BOR acts at 2.7v
' CONFIG WDT=ON, WDTPS=128
' ; WDT off
' CONFIG STVR=ON, LVP=OFF, DEBUG=OFF
' ; Stack over/underflow reset enabled
' ; LVP disabled
' ; Background debugger disabled
'endasm

This is the 18f452.inc file which, as mentioned, works

Any insight into the problem would be a help.
