This problem is caused by interaction between UNIX and VMS program return
values.  UNIX treats 0 as success, and non-zero as an error.  VMS has
a more complicated scheme, using the bottom three bits to hold the severity
of the error.

Eunice does a very half-hearted job of mapping UNIX onto VMS status.
It maps return of 0 to a VMS return of 1 (Success)
and passes any non-zero UNIX return through as it stands.
Most UNIX utilities return error codes of 1,  which comes through
looking exactly the same as a successful return.  This makes
writing VMS scripts using UNIX utilities very difficult.  The DCL
script to run the CC command is a case in point.

Has anybody out there done any fixes in this area?
