10 Arguments:
11 path1, path2
12    are the relative or absolute pathnames of the source programs to be
13    compared.  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.

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.  Vertical white space inserted or deleted between statements is
22 not ignored.  The line numbers in the compare_ascii output is not
23 accurate due to possible white space or statements broken over lines.
