Darrel,

I was able to mix the code example you provided with my previous code and I have almost completed my project. I have one final step to acomplish and it is to trigger off LED1 to 6 based on a time period. the time period is between 1 to 12 hours and can occur only every 60 minutes from the time LEDx was set high.

I came accros your example "Elapsed Timer" using Timer1 and I think this is suitable for what I need to do. I have saved the 3 files "DT_INTS-14.bas", "ReEnterPBP.bas" and "Elapsed_INT.bas" and used your example but I am getting the following errors:

[224] local directive only for use in macro
[225] undefined symbol 'iflafreg'
[226] numeric constant or symbol name expected
[201] ')' expected
[300] too many errors

Could it be that chip 16F883 is not supported with this code ?
I am using PBP 2.50c

Thanks

Mike
