And the version you have has the pCode peep hole optimizer disabled,
otherwise your program would've taken negative instructions! BTW, those
verbose debugging messages in the .asm will be gone by the time 2.4.0 is
released. Also, if you want to use MPASM instead of gpasm then do this:

sdcc -S -mpic14 file.c

The -S will compile only and generate "file.asm".

Then a .hex and .cod file can be generated with MPASM.

Sounds good. I hope the rest of the testing goes as smoothly as your
initial setup!
