Yes you can pass command line arguments.
How you do it, depends on what system you're using,
but on the vax you can use the pragma command to import a procedure
from the system called LIB$GET_FORRIGN, this allows you to access any
command line parameters passed.

Correct me if I am wrong, but passing command line parameters is *VERY*
implementation specific (I am assuming Ada83). I assumed "A.15" is a
reference to appendix A in the ARM. But, that was not what I found
there. Could someone please point me to the language (Ada83 or Ada9x)
this applies to and where in the ARM it it.

Unfortunately, the Ada95-team decided to change the letters of the
appendices/annexes. I ate it but unhappily.
In Ada83 the letters were easy to remember
A for Attributes, B for (Bragmas :-) Pragmas, etc.
In Ada95 you could have R for real-time, D for distributed,
F kept for implementation-dependent (chap13) and so on.
They have preferred other criteria.

Peter, there were all sorts of constraints in numbering annexes, including
some formal ISO rules. We discussed this at length. In particular, your
R for real time could not fly unless there were annexes A-Q :-)

A similar package for Ada83 can be found in the ADAR 2.0 components.

^^^^^^^^^^^^^^^
I've never seen a better Rationale as to why
Ada 95 has Ada.Command_Line :-)

Frustrated with C/C++, Pascal, Fortran? Ada95 _might_ be for you!
For all sorts of interesting Ada95 tidbits, run the command:
"finger dweller@starbase.neosoft.com | more" (or e-mail with "finger" as subj.)

You should check out the new getopt package that Perl5 comes with. That shows
how a good command line package could have been done. Of course the age old VMS
command line stuff is more advanced (and informal standards are adhered to:
it is very rare to have to worry about how to get out of a VMS program).
The command_line package is better than nothing, but the times are changing.

Actually, the excerpt below seems to be from a slightly
older version. In version 5.95, the type is called
"Exit_Status" and the routine to set it is called
"Set_Exit_Status".
So "Exit_" should be inserted as indicated below.

Actually, Argument_Count is equivalent to argc-1. That is, it is
a count of "arguments" and does *not* include the command name itself.

Actually, Argument(N) for N in 1..Argument_Count is
equivalent to argv[n] for (n = 1; n < argc; n++)

Right.

the correct name is LIB$Get_Foreign
and you don't need to import the procedure if you use VAX Ada version >=
2.0: it is in the VAX-Ada supplied package Lib and it's full Ada name
Lib.Get_Foreign.
