1 PRINT
  Syntax: PRINT id [&idb]
   where: id  is the histogram identifier
          idb is the (optional) secondary identifier

  Prints a histogram on the terminal or in a file. The output is set using
  the `SET DUMP' command.  If you want to make a  line printer copy of the
  histogram, use the commands:

  SET DUMP LPT
  PRINT id [&idb]
  SET DUMP CLOSE

  Then either `SHELL' or `SPAWN' a print command or go to another
  session and print the file `mn_dump.dat'. You can change the
  filename with the `SET DUMP FILE' command.
