Subject: An equilivant to Pascal's WITH in Ada??
Message-ID: <9104210400.AA06564@ajpo.sei.cmu.edu>
List-Id: <comp.lang.ada>

     In the process of translating Pascal, Turbo 5.5, code to Ada, Meridan, I
and the other members of my class group found that there was no equalivent to
the pascal WITH statement.  After some discussion we could not think of any
reason why the facility would cause *bad* programming practices.  The
posibility of placing each data structure in a package and then WITH/USEing
the structure was proposed, but this then makes the structure visable to
the entire package or procedure that USEes it.  This is not the desired
effect.

     Has anyone else faced this problem, I would think this question has been
asked before now.  If so what was the method used or why would a pascal WITH
structure be undesirable in Ada.

Example ( In Pascal ):
..
Type
  PersonRec  = Record
                 Name : String;
                 Age  : Integer;
                 ID   : Integer;
               end; { PersonRec }
..
Var
  Person     : PersonRec;
..
  WITH Person do
  begin
    Name := 'Asdfg';
    Age  := 24;
    ID   := 123930;
  end; { with person }
..

Any help would be appreciated as the code we are translating makes extensive
use of this feature and we feal that ada should, bar any opposing rational,
offer this feature.
