ABOUT: Verb-like to lists of verbs and tasks by category


DOCRT             -2.0       132.0 >= -1 => use terminal
                                   < -1 use line printer
                                   Printer disk file to save
                                   Desired version of this info
          The identity of the information desired must be given
          as an immediate argument, i.e. ABOUT APCLN.


Type: Pseudoverb
Use:  Causes helpful information to appear on your terminal or
      the line printer.  The grammar is

                    ABOUT nnnnnnnn

      to display the list of adverbs, verbs, procedures and
      tasks related to topic nnnnnnnnn.
  DOCRT.......Allows the output to go directly to the line
              printer if DOCRT < -1.  Else the terminal is used.
  OUTPRINT....Disk file name in which to save the line printer
              output.   ' ' => use scratch and print immediately
              for interactive jobs - batch jobs use OUTPRINT =
              'PRTFIL:BATCHjjj.nnn' (jjj = job #, nnn = user #).
              When OUTPRINT is not blank, multiple outputs are
              concatenated and the file is not actually printed.
  VERSION.....Version of ABOUT information desired, i.e.
              'OLD', 'NEW'.  See HELP VERSION for details.
