Here's a workaround in case your Concat is pervasive and you
don't want to muck in your source too much.

--------------------------------------------------------------------------

MODULE t;
FROM String IMPORT Assign;
IMPORT String;
FROM SimpleIO IMPORT WriteString,WriteLn;

(*
 * ...so then the C programmer says:
 * "if you make them VAR parameters,
 *  it'll run 10 times faster!"
 * :-)
 *)

PROCEDURE Concat(     first, second : ARRAY OF CHAR;
	          VAR out : ARRAY OF CHAR;
                      ok  : BOOLEAN );
BEGIN
  String.Concat( first, second, out, ok)
END Concat;

(*===============================================*)

VAR
  result:ARRAY [0..255] OF CHAR;
  rcode:BOOLEAN;
BEGIN
  Assign("bbb",result,rcode);
  WriteString(result);
  WriteLn;

  Concat("aaa",result,result,rcode);

  IF NOT rcode THEN
    WriteString("Failed");
    WriteLn;
  END;

  WriteString(result);
  WriteLn;
END t.
