-There's a built in system call to handle the generation of 24 bit
-CRC's (at least in 6809/OS9....I''m sure there's something similar in
-os9/68000 as well).

 I didn't have all the details of what he was trying to accomplish, but,
 what he needed was a C (or 680xx) version of the CRC24 routine for a 6809
 cross assembler that he was trying to get working on his Amiga.  He did
 end up using the F$CRC routine (by disassembling it), and converting it
 into C code.

  Thanks for the response,
