Help -- Command line arguments

[Stephen M O'Shaughnessy]

Is there a way in Ada to pass commands from the command line
when a process is started?

Since you didn't say, I'll assume you're using Ada 95. In that case,
what you want is in package Ada.Command_Line. For Ada 83, the Standard
was silent on the subject, but most Ada 83 compilers came with
vendor-specific packages to do what you want. If you're not using Ada
95, you should say which compiler you are using (not to mention which
platform) and someone can then tell you what the package is called for
that vendor's version.

There's a standard way in Ada 95 (Ada.Command_Line, I believe) and
various non-standard ways in Ada 83.

Actually, on my specific implementation (Verdix SELF on AIX), there is.
There's a demo program supplied with the compiler to do that, but
basically what
it does is declare ArgV and ArgC as PRAGMA INTERFACE variables, and the
startup
module (which is written in C and linked to the application) actually
declares and
allocates them, and initiailzed them.

The way the are used is like in C, ofcourse.

If you're not using SELF, check your example directory.

                      Best of luck,

You can see an example in my post  Re: Recommended way of reading file as
byte blocks
Hope this helps.

See Ada.Command_Line ARM A.15

For example,

with Ada.Command_Line;  use Ada.Command_Line;
with Text_Io;  use Text_Io;
 
procedure X is
 
begin
    Put_Line(
        "My name is " & Command_Name & ", I have" &
        Integer'Image(Argument_Count) & " arguments.");
    Put_Line("They are: ");
    for I in 1..Argument_Count loop
        Put_Line("  " & Argument(I));
    end loop;
end;

$ gnatmake x.adb
$ x 1 2 3
My name is x, I have 3 arguments.
They are: 
  1
  2
  3
$
