Bert,
	Yes, Alsys does provide such a package, SYSTEM_ENVIRONMENT.  Off the
top of my head I can not recall the exact operation names, but it allows you to
access the argument count, the argument values, run system commands, get exit
codes, suspend Ada tasking and resueme it etc.

	My question to you is, do you have to go to Alsys?  Unless it is
necessary I would not recommend it over Verdix.  The compiler and library
operations are far from intuative, the debugger handles taksing worst then the
Verdix debugger, and there are several compiler bugs that I have not seen in
Verdix.  From my understanding, Verdix is also far more responsive to problems
with their stuff then Alsys.

	If you have no other choice then to use Alsys Ada, I guess there is
nothing you can do.  If you do have a choice, however, remember even divisions
of Alsys do not recommend their Ada compiler!
