    Procedure:  _pwgetun.p
    
    Purpose:    Returns a Procedure Window Untitled procedure name.
    
    Syntax :    RUN adecomm/_pwgetun.p ( OUTPUT p_Untitled_Name ).

    Parameters:
    Description:
        An Untitled Procedure Window has a procedure name of the form
            "Untitled:n"
        where n is some number from 1 to 9999.
        
        The untitled name algorithm:
        
          1. Search all the windows in the current session looking for
             Untitled Procedure Windows, regardless of how a Procedure
             Window was created.
             
          2. Return the maximum Untitled procedure number plus one as
             the next Untitled procedure number.
             
             For example, if there are two open Untitled PW's, Untitled:1
             and Untitled:5, the name of the next Untitled PW will be
             Untitled:6.
