          The identity of the information desired may be given
          as an immediate argument, i.e. HELP APCLN.  If no
          immediate argument is given TASK is used with ' ' =>
          HELP which lists special kinds of files to provide
          additional information and lists.

HELP SECTION

HELP
Type: Pseudoverb
Use:  Causes helpful information to appear on your terminal.  The
      grammar is:

                    HELP nnnnnnnn

      to list information about the individual verb, adverb, pseudoverb,
      or task named (in nnnnnnnn).  Additional informative HELP files
      are listed below.  Lists of tasks, verbs, adverbs, and procedures
      by category may be displayed with the ABOUT pseudoverb (see HELP
      ABOUT).  Some tasks have additional usage information which is
      shown by the EXPLAIN pseudoverb.

      The AIPS CookBook is the primary source of information about
      AIPS.  Each installation of AIPS contains the CookBook in the
      directory $AIPS_ROOT/TEXT/PUBL with each chapter in PostScript
      form named COOK?.PS (? = chapter number or appendix letter).
      The full CookBook in pdf form is available as well.  It is named
      COOKBOOK.PDF and allows you to search for strings, follow
      section and index links, and even look at HELP files in your
      browser.  Use the adobe reader - cheap imitations do not work as
      well.

      If this directory is not readily available, you may also use the
      web to get at the CookBook.  The web page
             http:www.aips.nrao.edu/cook.html
      takes you to the table of contents.  The first paragraph of this
      page has links to the full cross-referenced versions of the
      CookBook in html and in pdf.

Adverbs:
  TASK........If no immediate argument is given, TASK names the object
              (task, verb, adverb, procedure, etc.) to be described.
              ' ' => HELP (this file).
  DOCRT.......Allows the output to go directly to the line printer if
              DOCRT < -1.  Else the terminal is used.
              With OUTPRINT not blank, DOCRT=-3 suppresses the
              page-feed character in header lines; DOCRT=-4 suppresses
              the header lines except at the beginning.
  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 HELP information desired, i.e. 'OLD', 'NEW'.
              See HELP VERSION for details.
