Hello all:

I'm trying to write a program that takes from command line arguments the
name of file to proccess.  I use the command_package

For some reason I get a CONSTRAINT_ERROR when I try to assing Argument(
2 ) to a string: here is the code

with ADA.Command_line;
use Ada.Command_Line;

procedure com_line is
a : String (integer range 1..100);
begin
        put( Argument_Count );

        -- Here is the error:
        a := Argument( 2 );
        put_Line( a );
end prueba;


I can't understand why this happens, but when I do:
tajo:~/temp4$ ./com_line hello1 hello2 hello3  hello4 hello5 hello6
        7
raised CONSTRAINT_ERROR : com_line.adb:14

I use the gnat compiler for linux

Regards
    Pedro
