This is VERY system-dependent. VMS, for instance, supports a consistent
calling interface between languages, altho there are a few gotchas. Some
of the other vendors do this also (MicroSoft, bless their pointy little
heads, claims they do this, too (Ive never tried]. But sharing "commons"
should be fairly portable. It would be helpful if you mentioned OS, HW,
and any portability requirements.
