Help: Main program parameters

[russell@mdavcr.mda.ca (Norman Russell)]

Hi there,

Is it possible to have a main ada procedure (program) with parameters?

For example, my main program is called: Read_Text  and I would like
to call that main program (from the command line) with the name of
the file I want to read.

I thought I would be able to have my main procedure has follows:

procedure READ_TEXT (File_Name : in STRING := "") is
begin
  .
  .
  .
end READ_TEXT;

This compiles nicely, but when I go to link it I get the following
error message:

%ACS-E-CL_MAIUNISIG, Main unit READ_TEXT has parameters or a result type that
        are not supported for a main program

Does any body know how I can make this so I can just type from the
command line:

   $ READ_TEXT My_Text_File.TXT

and it will understand I want to read the file called "My_Text_File.TXT"

In case it helps I'm using the VAX ADA Compiler.

Thanks in advance!
