The source is "almost" compatible. The main problem is that the "." operator is used as an alias for "+". This can be cured by replacing the following strings in all ASM files:

  ". _low"     -> "+ _low"
  ". _high"    -> "+ _high"
  ". _pointer" -> "+ _pointer"
  ". _segment" -> "+ _segment"
  ". _AL"      -> "+ _AL"
  ". _DL"      -> "+ _DL"

this eliminates about 98% of the errors. Another 1.5% is eliminated by changing GoTo to @GoTo (GOTO has become a reserved word in Masm v6).

The small rest are trivial things (sometimes the space is missing between "." and _low/_high, once a STRUCT is defined "too late" and must be moved) which are easy to fix.

A brief test of the newly generated rxdoscmd.exe was successful.

It's not a bug. The problem with WLink is that it wants the decorated name for exports. And I'm not in the mood to calculate the @size prefix for about 1.000 functions and add it to the wlink response file (although, I vaguely remember a tool LIB2DEF which creates .DEF files from import libs and might be used for this task). Currently PoLink/MS link is still used.

It's incomplete, and it's documented that it's incomplete. RTFM! :-D
