#### Command Lists

After NeXtMidas is installed, these commands quickly provide explanations of concepts or commands: MENU, EXPLAIN, DEFAULT, HELP, HELP/GUI.

`MENU` provides an up-to-date list of all NeXtMidas commands available for execution.

`EXPLAIN <``command>` always gives the most detailed description about the calling sequence and performance of a specified command.

`DEFAULT <``command>` lists default values for <`command`>

`HELP` shows list of HELP categories

`HELP <``category>` lists routines, switches, or qualifiers in <category>

`HELP <``routine>` gives on-line documentation for <routine>

`HELP/GUI` is a graphic interface to EXPLAIN and HELP. The HELP/GUI is a simple way for beginners to learn their way around NeXtMidas. It is also helpful to Midas veterans who want to look up a detail or two without interrupting their current session.

This example brings up an interactive menu for browsing through NeXtMidas concepts. Type `HELP` at the NeXtMidas prompt:
