EXPLAIN

gives an explanation of a Midas command

<name>    - Name of Midas command (or its abbreviation)
<section> - Section of explain file to view (optional)

EXPLAIN outputs information about the calling sequence and performance of the
specified command.  The explanation will be shown a page at a time; when the
screen fills, you are prompted to press Return for more.  You can also press Q
at this prompt, to quit without seeing the rest of the explanation.

EXPLAIN assumes an explain file for the command has been written and placed in
the EXP area.

The <section> may be one of FUNCTIONS, MESSAGES, EXAMPLES, SWITCHES, SEEALSO or
any <NAME:> heading that is left aligned.  If it is not one of these, then it
may be a name in the FUNCTIONS section.

If <section> is left blank the entire explain file is viewed. If section is
"SeeAlso" the "See Also" section is displayed.

There are 4 predefined sections: "Messages", "Switches", "See Also" and
"Examples". Each of which begins with the name of the section followed by a
colon (e.g. "Switches:") and continues as long as the text is indented below it.
Please see the PLOT;SYS explain file for an example.

Examples:
  1. Display the entire explain file for the PLOT command:
    nM> EXPLAIN PLOT

  2. Display only the switches that can be used with PLOT:

  3. Display only the switches that can be used with PLOT:

  4. Display the PADX function in the SEDIT explain file
