Ok, I tried it, but it seems that a "subtype" is also not the solution:
package spec:
package Pkg is
subtype
Sixteen_Bits is Integer range 0..65535;
procedure Proc (Host : STRING; RC : out Integer; Identifier : in
Sixteen_Bits := 0);
procedure Proc (Host : STRING;
Time_Response : out Integer; RC : out Integer;
Time_Wait : Integer := 10;
Identifier : in Sixteen_Bits := 0);
end Pkg;
program:
with Text_IO;
with Ada.Command_Line; use Ada.Command_Line;
with Pkg; use Pkg;
procedure PkgTest is
RC : Integer;
begin
if Argument_Count /= 1
then
Text_IO.Put_Line ("call: PkgTest <ip>");
return;
end if;
Proc (Argument (1), RC, Sixteen_Bits (2507));
Text_IO.Put_Line ("RC=" & Integer'Image (RC));
end PkgTest;
> Or use two different names, instead of calling both "Proc".
No, that's not what I want. The advantage of Ada against other languages
is the overloading: that same things can have the same name(e.g. Put for
all types, unlike WriteInt, WriteCard ... in Modula).
