Recipe 6.2. Finding JOE Commands

How do you make JOE do anything useful? You want a complete command reference for JOE, in all of its personalities. And you want it online, so you can use it while you type.

6.2.2 Solution

Turn on the online help, which is present in every one of JOE's personalities.

To start up JOE with the Help screen turned on, use:

Do the same for rjoe, jpico, jmacs, and jstar.
