LITERAL  -  prefix 

Usage:  LITERAL [command]
  
LITERAL is actually not a command, but a prefix to the LIST, TYPE and 
  PRINT commands.  LITERAL TYPE is assumed if the command is omitted.  
  It is used to ignore the customization variables DONT-PRINT-HEADERS, 
  ONLY-PRINT-HEADERS, DONT-TYPE-HEADERS and ONLY-TYPE-HEADERS, which
  limit which header fields are displayed.  With LITERAL, all the 
  header fields are shown, regardless.

Examples:
    MM>set dont-print-headers received	#suppresses header field "received"
    MM>type 14	                  	#header field "received" not shown
    MM>literal type 14   	 	#header field "received" shown
