//  void EditDisplay( HWND hDlg,
//                    int control_id,

// C SYNOPSIS

//  #include "arclib.h"
//
//  void EditDisplay( HWND hDlg,
//                    int control_id,
//                    char *fmt,
//                    ... );
//
// VB SYNOPSIS
//
//  None, there is no VB for OS/2.
//
// DELPHI SYNOPSIS
//
//  None, there is no Delphi for OS/2.
//
// ARGUMENTS
//
//  hDlg   :  This argument is a window handle.  If the next parameter,
//            control_id, is set to -1, it means this is the handle of
//            the window that will have some new text written to it.
//            If control_id is some other value, it means this is the
//            handle of a dialog box, and control_id refers to an edit
//            control within the dialog box.  That edit control is the
//            destination for the text output.
//
//  control_id :  The id of the multiline edit control in a dialog box.  If
//                set to -1, it means the edit control is not in a dialog box,
//                and the hDlg parameter is the handle of the edit control.
//
//  fmt    :  The format parameter to be used in wsprintf.
//
//  ...    :  Any additional arguments that are going to be used by
//            vsprintf().
//
//
// DESCRIPTION
//
//  This little function lets you use a printf() style command to print
//  data to a multiline edit control.  The internal buffer is only 128
//  bytes, so please be careful.
//
// RETURNS
//
//  Nothing.
