Systemless use of 'Address.

[Bob Wells #402 <wel@EUROCONTROL.DE>]

G'day,

Given the following procedure declaration:

  procedure Display_Code2String (
    Data_Address : in     System.Address;
    Data_Size    : in     Natural;
    Data         : in out String_Ptr;
    Length       : in out Natural;
    Append       : in     Boolean := False);


and the following call to the procedure

        Draw.Display_Code2String ( Data_Address => Tmp_String'Address,
                                   Data_Size    => Tmp_String'Size,
                                   Data         => Return_String,
                                   Length       => Return_String_Length );

Why does the Verdix compiler (sorry specifically the

Verdix Ada Compiler, Copyright 1984, 1992
VADSworks for Sun-4 -> MC68020/30/vxWorks, (VADS 6.0.5)

accept this procedyre call **without** the a with clause for the package
System?

But if I add

        Tmp_String : EDD_Code_String ( 1 .. (Integer(Tmp_Seq.All'Last)/3 + 1));
        for Tmp_String use at Tmp_Seq.All'Address;

it now will only compile the package without errors if I "with" System?

Am I missing something here?

Thanks,

BTW I haven't forgotten the request for Ada ATC info Mike. I'll get back to
you as soon as I can.
