I have obtained a program from the Parallax Web Site called picsrc12.  It is
supposed to take INHX8M output from Parallax pasm and convert it to
Microchip mpasm source and vice versa.  The code is for a 16c57.  Converting
from mpasm to pasm seems to work, as long as the origin is zero.  The lables
for jumps and calls are not present if the origin is not zero.  Going from
pasm to mpasm creates a file that at the least is not formatted properly for
mpasm as below:

                    00015 ;                  include "picreg.h"
                    00016
Warning[207]: Found label after column 1. (INDIRECT)
  00000000          00017           INDIRECT  equ  H'00'
Warning[207]: Found label after column 1. (FILE_08)
  00000008          00018           FILE_08   equ  H'08'
Warning[207]: Found label after column 1. (FILE_09)
  00000009          00019           FILE_09   equ  H'09'

Also I don't know where to get the picreg.h file.

Does anyone have any experience combining code written with these two
assemblers using picsrc12 or any other method?

Thanks in advance.
