Pascal/MT+ & Assembler Question - CP/m 2.2 and Disk formatters

Hmmm. After bashing my head against the wall for a while, I have decided to ask the list for directions (It's kind of like blokes and driving...) I have a little STD Bus CP/M 2.2 system for which I am trying to install 3.5" disk drives - Yes I know about the diferent speeds etc - but I am happy to do whatever it takes....The hardware stuff isn't that complex, I am using a 1793 disk controller, and I have good software control of it - actually ---- That's not totally correct yet! The original formatter for the system was written in Pascal MT+ - I have the source. It uses a short external assembly program to do the tricky stuff. I can compile the formatter - yay! It produces an .ERL file as its ooutput - I can also link it (using the pascal MT+ linker) with PASLIB, but I get unresolved references (ie the assembler formatter routines) - no surprises there.. I can assemble the assembly formatter - M80 =FORM4A and I get a .REL file as output. The bit I am missing is how can I link the two outputs into a single .COM file. L80 barfs at the output of the Pascal file, and the pascal linker barfs at the Microsoft file.... Help :-) Doug
