The .pl1 suffix is assumed. The star convention is not 14 allowed; the equal convention is allowed for path2. Archive 15 component pathnames are allowed. 16 17 18 Notes: All format_pl1 control comments are removed from both programs. 19 Then, format_pl1 is used to put both programs into a canonical style. 20 The compare_ascii command is used to see how the source programs 21 differ.
