hi,
 we run vs pascal 2.1 on vm/sp 6.  is it possible to pass as a procedure
 parameter a procedure name with a parameter list?  for example,

program main (input,output);

var word: packed array(1..5) of char;

procedure abc(procedure xyx(var string: packed array(1..5) of char);i:integer);
          .
          .
procedure blah(var string: packed array(1..5) of char);
          .
          .
  begin (* main program *)
          .
          .
   abc(blah(word),3)
  end.

i can pass procedure names without parameter lists as parameters to a
procedure, but i get errors using the above code.  i don't know if this
is a restriction on our particular product or not.  the pascal report
(wirth & jensen) seems to indicate you can do this.  does anyone have an
example of code where this has been successfully done?  any help is
appreciated.
