Ops5 Files

The OPS5 source code is in this directory in the file ops5.l.  A compiled
version is in the file ops5.b.

To use OPS5, use the HP-UX command ln to link $aicontrib/ops5/ops5.b
to /lisp/modules/local/ops5.b.  Then, from Common Lisp, execute 
(require "ops5") whenever you want to use OPS5.  If this does not work,
recompile the source code and relink it.  There are two symbols, namely
remove and write, which occur in both the lisp and ops5 packages.  If you
are using OPS5, you probably want to give precedence to its definitions of
these symbols.  To do so, execute the Common Lisp form
(shadowing-import '(ops5:remove ops5:write)).  Then execute (use-package
'ops5) or preface calls to OPS5 facilities by ops5:.  If you fail to
do the shadowing-import, you will generate a continuable error to deal with
the package conflict.  If you have HP Prolog present in your dump file, there
are more symbol conflicts.  Handle them in the same way.

No on-line documentation is provided.  An excellent source of information on
OPS5 is the book
