Thanks for the answer -- now, for a followup question:  do the Ada interface
packages to other languages all assume that the other languages follow ABI
as well?  I've wondered how Ada compiler X can know how to call a function
created by C compiler Y, but if ABI is assumed on both ends it would make
sense.

Is there, then, exactly one ABI per architecture, as would seem to be
necessary?  How and where are these standardised?

Again my thanks to the helpful folks on this group -- maybe someday *I'll*
be able to answer questions here!

Mike
