BIORTH %2(5)

     BIORTH is a program to  chart  biorhythms.   It  is  reported  that
through  biorhythms  one  may fortell one's attitudes based on his (her)
emotional, physical and intellectual cycles.

     BIORTH uses verb-like commands.  Allowable commands are:

     1.  BEGIN DATESPEC
         Sets the beginning date for the biorhythm chart.  If  no  BEGIN
         date is specified, today is used.

     2.  BIRTHD DATESPEC
         Use the specified birthday when charting the biorhythm.   If  a
         PLOT  command is given before a BIRTHDAY command, an error will
         result.

     3.  CHART DEV:FILE.EXT
         This is the same as the PLOT command and is included  only  for
         convenience.

     4.  COMPATIBILITY (abbreviate to COM)
         You will be prompted  for  two  birthdates.   The  output  will
         consist  of the compatibility percentages for each of the three
         areas (emotional, intellectual, and physical)  and  an  overall
         average compatibility.

     5.  END DATESPEC
         Set the last date to chart in the biorhythm.  If no ending date
         is  specified,  the default is to go forever if charting to the
         teletype, or for one month if going to a disk or  line  printer
         file.  If the date specified by the END command is earlier than
         the date specified by the BEGIN command then the plot  will  go
         backwards in time.

     6.  PLOT dev:file.ext
         This  is  the  command  which  actually  does  the  plot.    If
         DEV:FILE.EXT  is  not  given,  the chart will be plotted on the
         teletype.  This command may be modified by the /END and  /BEGIN
         switches:

                   PLOT/BEGIN:TODAY/END:+7D

         THIS WOULD PLOT ONE WEEK, BEGINNING WITH TODAY, AND  ENDING  IN
         ONE WEEK, ON THE TELETYPE.

                   PLOT/BEGIN:1-JAN-77/END:30-JUN-76

         This would plot beginning with January  1,  1977  backwards  in
         time to the 30th of June, 1976 on the teletype.


     Allowable formats for the datespec are:

     1.  DD-MMM-YY
         THIS IS THE NORMAL FORM.  FOR INSTANCE, 19-APR-52  MEANS  APRIL
         19, 1952.

     2.  NNND
         THIS SPECIFIES THE DAY AS A NUMBER.  THIS IS  USUALLY  USED  IN
         CONJUNCTION WITH "+" (NNN DAYS IN THE FUTURE FROM TODAY) OR "-"
         (NNN DAYS IN THE PAST FROM TODAY.
