                                 L_CHKSCR()


Syntax:        L_CHKSCR(<expC1>[,<expC2>][,<expN>])


Purpose:       To investigate the contents of a file created by the
               L_SAVESCR() function.


Arguments:     <expC1> is the name of the file.

               <expC2> is the optional name of the screen for which to
               search.

               <expN>  is the optional position within the file at
               which to locate a particular screen.


Returns:       If a particular screen is specified and found then the
               position within the file, the screen name and screen
               size are returned. If nothing is found then an error
               message is returned. If both the optional parameters
               are ignored then a list of all the screens in the file
               is returned.


Usage:         To study the contents of a file created by L_SAVESCR().
