a better way (at least if you want to look and feel like a VAX command)
is to use the VMS command line interface routines (CLI).  This allows
you to define you command line syntax/defaults and rules about
which qualifiers go with others etc in a text file instead of your program.
you get default VMS behavior regarding abbreviations - prompting for missing
params etc, your application looks just like it came from DEC.
(foreign commands look just like that "foreign" to the VMS environment)

VMS Ada provides a package called CLI which serves as an Ada interface
to the CLI routines (use acs extract source to see it) its in every Ada
library (not sublibrary)

the spec isnt terribly readable, you probably should read the manual.

the name of the manual you want is the VMS Command Definition Utility Manual.
