DESCRIPTION

The prev command is used to display the previous message in a folder.  This
command is equivalent to the show command with prev specified as the message.
The prev command is part of the Message Handling (MH) package and can be used
with other MH commands.

The prev command links to the show program and passes this program its flags
and attributes.

Note:  If you link to the prev command and call that link something other than
       prev, your link functions like the show command rather than the prev
       command.

The show command invokes a program to perform the listing.  The system default
is /bin/pg.  You can define your own default with the showproc: entry in
$HOME/.mh_profile.  If you set showproc: entry to mhl, the show command calls
an internal mhl routine instead of the mhl command.  You can also specify the
program to perform a listing in the cmdstring of the -showproc flag.

The show command passes any flags that it does not recognize to the program
performing the listing.  Thus, you can specify flags for the listing program,
as well as the flags described in this command section.
