[ NOTE:  The limitations described in the first paragraph of this
original DOC file no longer apply.  Install for any terminal using
the INSTALL.COM program provided.  You may re-name the program
after installing it, but the installation program can only install
the program when it is named AXCAL87.COM.  If you want to use this
program in an MS-DOS environment, you won't have to install it at 
all -- just use the file CAL87IBM.COM.  It is pre-configured for
a monochrome display.  Note that all of the files must be uncrunched
before use.  ]

CAL87.COM is a greatly altered and improved version of Calendar.Com, a full-
screen monthly appointment calendar, written in TURBO PASCAL for an 80 column
Osborne 1 or VIXEN.  It uses direct screen addressing, so it won't work on any
other machine (but it can be changed to work on the Executive with one simple
change to the source code).  It's good to the year 2100.

At the "A>" prompt, type "CAL87" to run it.  (Rename it to a simpler name if
you want).  It will load 1987's dates.  If you want to load a calendar with any
other year's dates (not before 1985!), type "CAL87 1989" or "CAL87 89" or
"CAL87 2001", etc.  ("19" is added in the program to any 2-number year input). 
To avoid having to type in the current year (after this year), find "1987" in
the program with Edfile.Com or a similar program, and change it to the current
year.  It is only written once in the program, and the string to search for
(using Edfile) would be C3,07 (1987 in Hexadecimal, reversed).

In the program, at the "Month:" prompt, type in the month (only 3 letters
are required) and press RETURN, or press RETURN to exit to CP/M.

Commands when in a month are similar to commands in WordStar.
Move the cursor with:
  Ctrl-F Right a Day
  Ctrl-A Left a Day
  Ctrl-R Up a Day
  Ctrl-C Down a Day
  Ctrl-D Right a Character
  Ctrl-S Left a Character
  Ctrl-E Up a Line
  Ctrl-X (or RETURN) Down a Line
  Ctrl-G Erase Character at Cursor Position
  Ctrl-H Erase Character to Left of Cursor
  Ctrl-Y Erase Line
  Ctrl-QD To Right of Calendar
  Ctrl-QS To Left of Calendar
  Ctrl-QE To Top of Calendar
  Ctrl-QX To Bottom of Calendar

Exit the month with Ctrl-K (or ESC).  You will be prompted with the question
"Save (Y/N)?".  Any input besides "N" or "n" will set a Save Flag in the
program so that all months will be saved when you finally exit to CP/M.  The
Save Flag Set is indicated by an "S" in the upper left-hand corner of the
screen after you have exited the month.

Print the screen on the VIXEN with the SHIFT-BLANK key, or on the Osborne 1
with the key you set up for this with PATCHER.COM (you have to have this
program if you have an O1!).

A data file called "CAL87.DTA" (or "CAL99.DTA" if the year is 1999, etc)
will be saved on the logged disk, if you saved any month.  This file will be
loaded with the program if it's on the same disk as the program, and if it's
for the year you indicate when running the program.  To insure that the data
file will be saved and loaded on the same disk as the program, only run the
program directly from the logged disk drive, and NOT like this: "A> B:CAL87"
The data file is in the format:  Month Day Row
