FIT48 - Fitness PIM for the HP48G
                        Version 1.0
                      Library ID 1496


  FIT48 is a personal information manager for tracking health and
  fitness. It maintains a daily database of weight, calories consumed,
  and fat grams consumed. FIT48 provides graphical and tabular
  displays of information from the database.

  Note: FIT48 requires an HP48G or HP48GX series calculator. It will
  not run on an HP48S or HP48SX.

  FIT48 is NOT public domain software. It is copyright (c) 1994 by
  Stephen A. Thomas. You are free to use the library for any purposes,
  however, provided,

  1) You don't sell it. (If you distribute the library, you
     may charge a reasonable fee for materials, shipping, and
     handling. You must also include this copyright notice and
     license with all copies.)

  If possible, I would also appreciate it if

  2) You drop me a line (sat@eng.tridom.com) to let me know what
     you think. Constructive criticism is encouraged. Please let
     me know about any bugs or defects!


 Installing the FIT48 Library
----------------------------

  1. Download FIT48.LIB to your HOME directory in binary mode.
  2. Press [VAR] ['] |FIT48.LIB| [ENTER] [ENTER] [RIGHT-SHIFT] 
     [RCL] [LEFT-SHIFT] [SWAP] [LEFT-SHIFT] [PURGE] 0 [STO]
  3. Turn off your HP48 and turn it back on again.


Using the FIT48 Library
-----------------------

  To access the FIT48 main screen:

     1.  [RIGHT-SHIFT] [LIBRARY]
     2.  |FIT48|                    (cycling through [NXT] if needed)
     3.  |FIT48|

  The first time you run FIT48, it displays a copyright screen
  for a few seconds. Next it asks you for your current weight. FIT48
  then creates a new variable, 'fPAR', in your home directory. All
  information that FIT48 maintains is stored in that variable.

  The FIT48 main screen displays current (today's) information. An
  example screen is shown below.


          ########  FIT48 - WED 03AUG  ########

            Weight:     192 (-13)
            Today:      800   5g   6%
            Tue-Tue:   1687  27g  14%

          ABOUT  SCALE  EAT  TABLE  PLOT  QUIT


  The information in this screen includes your current weight (192 
  lbs) and the difference between that weight and your starting 
  weight (13 lbs). The next line shows the number of calories
  (800) and fat grams (5) consumed today. It also computes the
  percentage of calories from fat (6%). The following line
  shows the same information averaged for the seven days prior
  to today. The example shows the average for the 7 days between
  26Jul and 2Aug, inclusive.

  The menu keys perform the following functions:

  |ABOUT|  Shows copyright and version information; press any
           key to return to the main screen.

  |SCALE|  Allows you to enter today's weight using a standard
           HP48G form. (The first time FIT48 is run on any
           given day, it automatically sets the current weight
           to be the same as the previous day's weight. Use this
           command to enter a new weight.)

  | EAT |  Allows you to enter calories and fat grams for a meal,
           using a standard HP48G form.

  |TABLE|  Creates a table of all information (date, weight, calories
           consumed, fat grams, and % calories from fat). The table
           is viewed using the PICTURE environment. Press [CANCEL] to
           return to the main screen.

  |PLOT |  Creates a bar plot of weight, calories consumed, or fat
           grams. The plot is viewed using the PLOT environment. Press
           [CANCEL] or |CANCL| to return to the main screen.

  |QUIT |  Exits FIT48, giving you the option of accepting or ignoring
           any information entered in the current session.

  Two other keys are also active in the main screen.

  [CANCEL]            - same as |QUIT|
  [LEFT-SHIFT] [EDIT] - lets you select a specific day's data (today or
                      a previous day) to edit.

  Other library commands:

  |W->DY|   Given a desired weight (in level 1), predicts a date at which
            that weight will be reached. The result is based on a linear
            regression of the current data assuming a linear fit.

  |FIT->S|  Stores the current FIT48 data in 'SDAT' (where S represents
            the summation sign) in the current directory. This lets you
            perform your own statistical analysis on the data. The format
            for the data is:
          
              col 1:  day number, starting at 1
              col 2:  weight
              col 3:  calories consumed
              col 4:  fat grams consumed
              col 5:  percent calories from fat

  |FINIT|   Re-initializes FIT48 with a new starting date and starting
            weight.

  |ABOUT|   Shows copyright and version information.
