Using command-line arguments

Using command-line arguments

[Kai Glsner]

Hello Community,

I have a question concerning the usage of command-line arguments in Ada. For
the start I try to give my main-routine two integer-values using
Ada.Command_Line.Argument (). But this  function gives back a string...

How can I deal with strings (or options), integers and floats as
command-line arguments

Thanks in advance for the answer.

with ada.command_line;
with ada.text_io; use ada.text_io;

procedure test is
begin
  put_line(Integer'value(ada.command_line.argument(1)));
  put_line(Integer'value(ada.command_line.argument(2)));
end;

Sorry, my mind collapsed for a moment. The contents of put_line
was correct, but put_line only takes strings as parameters.
The example under is hopefully better. It compiles at least.

with ada.command_line;
with ada.text_io; use ada.text_io;

procedure test is

A, B : integer

begin
  A := Integer'value(ada.command_line.argument(1));
  B := Integer'value(ada.command_line.argument(2));
end;

Usually, there is a simple way to do most things in Ada. It just
requires some experience with the language. You might try looking at the
Adapower website (www.adapower.com) for additional help & examples of
how to do various things.
