The documentation that comes with ACL, which is in HTML, and can be found on the CS Unix machines by starting with /lusr/lib/franz/acl60/doc/introduction.htm.
You may run ACL in two ways:
See trace file of running ACL in Emacs. See Allegro tips for a few tips on handling errors, aborting executions, and loading and compiling files. For a longer list of ACL commands have a look here. Also browse the items that ACL adds to the Emacs menu.
If you are unfamiliar with the Emacs text editor, it is executed with the
UNIX command emacs. See web pages on Gnu Emacs such as the
department Emacs info or others like this Emacs Tutorial
or get the official manual:
GNU Emacs Manual, R. Stallman, Free Software Foundation (order page).
GCL is available on IBMs and SUN SPARCs. The executable is /p/bin/gcl. You simply type lisp or gcl to execute GCL. You may also run GCL as a subprocess of Emacs. In this case, follow the same procedure as in running ACL in Emacs but this time issue M-x run-lisp command to load GCL.
