Guys....

I have a problem.... I have just started with 24F's in ASM30 and have run
into a stubborn issue. I have a simple piece of code that kicks a text
display into life.=20

The main code operates from the reset to the first call to a subroutine tha=
t
is in an included file. At this point the simulator goes back to the __rese=
t
line in the main source code instead of switching to the included file. If =
I
have the code in line in the main file it simulates properly. It does this
with both MPLAB Sim and ICD3.=20

When ICD3 is the target the program runs on the device properly it also
displays as expected in the disassembly listing.

This was never a problem with and 8 bit device and I cant drive 'C' yet and
there is very sparse web recourses on ASM30 at all...

Thanks in advance
