PREVIOUS  -  display the previous message

Usage:  PREVIOUS

The PREVIOUS command makes the message before the current message become 
  current, and displays it.  Like the TYPE command, it does not enter READ
  mode, so you are back at the TOP-LEVEL prompt (MM>) after seeing the 
  message.

For more help type "help" and one of these topics:
  message-sequence   read   next   type   other
