Vcalendar is a calendar/schedule keeping program that allows one to
keep track of appointments, classes, meetings, and dates, etc. It is
posted upon request from panetta at duphy4.drexel.edu. Vcalendar is
written in C running on VAX/VMS 4.xx or higher. It is free.

If you are interested, please cut the three parts - VCAL1.SHAR,
VCAL2.SHAR and VCAL3.SHAR; follow the instructions in 0REAME.1ST and 
have fun.

	X                                    Abstract

	X

	X     If you forget your dates or are late on your appointments most of  the

	X     times, VCAL may be the right tool for you.

	X

	X                                    History

	X

	X     There have been many versions of VCAL.  One of those written  by  Mike

	X     Essex  at  Berkeley.   His version, which has been reported to work on

	X     UNIX Version 7, BSD 4.3, and ULTRIX, was written in C using  C  curses

	X     and  Termcap.   It could, perhaps, be ported to VAX/VMS without making

	X     changes.  However, excellent VAX/VMS screen  management  features  are

	X     not  fully  utilized;  therefore,  VCAL was then C-modified using SMG.

	X     There are differences and similarities between UNIX C and VAX C; and C

	X     curses and SMG.  However, they are not discussed here.

	X

	X                             VAX/VMS VCAL Features

	X

	X     VCAL provides you a calendar of each month.  From this  calendar,  you

	X     can  pick  any day to record appointments (Day Picking Phase).  When a

	X     day is picked, you enter the second phase (Appointments Making Phase).

	X     You  can  switch  back  and  forth  between these two phases.  You can

	X     record 17 appointments for a day.  The length of each appointments  is

	X     60  characters.   Just  think  that you are using a calendar pad.  The

	X     design was based on this philosophy.  It sounds complicated, but don't

	X     worry!   The  software  is a menu-driven one, so it will help you when

	X     you go along.  You just have to pay attention to the small help window

	X     in the lower left-hand corner.

	X

	X     That's not all.  VCAL does also provides you the reminding service for

	X     today  if  you  want.   Before  the  appointment  time approximately 5

	X     minutes, it will beep  at  your  terminal,  displaying  the  scheduled

	X     activity you had recorded before.

	X

	X     That's  still  not  all.   VCAL,   furthermore,   provides   you   the

	X     appointments  summary  for any month between the year 1900 and 9999 if

	X     you want.

	X

	X     Finally, when your appointments file grows bigger until it reaches the

	X     threshold  size,  you  will  be notified to purge all old appointments

	X     leaving only appointments for the current month and the future ones.

	X

	X     What does it cost you?  Nothing!  If you are interested, then continue

	X     reading.

	X

	X                             VAX/VMS VCAL Commands

	X

	X     1) To record appointments, please type:

	X

	X     $ VCAL

	X

	X     Then follow the instructions provided in  the  small  lower  left-hand

	X     window.   When  you  complete  and  exit, the file APPOINTMENTS.DAT is

	X     created in your main directory.  DONOT delete this file.  It is  where

	X     all   appointments   are  kept.   If  you  frequently  purge  all  old

	X     appointments, the size of this file will be at maximum 1 block.

	X

	X     2) To ask for reminding service for today:

	X

	X     $ VCAL/REMIND/MIN=[min]     /* 5 <= min <= 20 */

	X

	X     A sub-process is created.  It hibernates until approximately 5 minutes

	X     before  each  appointment  for  that  day,  wakes up reminding you the

	X     scheduled event,  then  goes  back  into  hibernation  until  no  more

	X     appointments.   The  sub-process  then terminates.  In terms of system

	X     resources, it doesn't bog down any  thing  because  when  the  process

	X     hibernates,  it  is  swapped  out  of  memory.   When you log out, the

	X     sub-process  is  automatically  terminated  also.   If  you  want   to

	X     terminate this sub-process instead, just type:

	X

	X     $ STOP REM_username     /* For example, $ STOP REM_CS100002 */

	X

	X     3) To ask for an appointments summary for a month, please type:

	X

	X     $ VCAL/SUMMARY

	X

	X     The summary for this month's appointments will be displayed on screen.

	X     You can re-direct the output to a file by typing:

	X

	X     $ VCAL/SUMMARY/OUT=[file]

	X

	X     You can also add the qualifiers /MON=[month], and /YEAR=[year] to  the

	X     command.   Month is any month.  i.e., JANUARY, FEBRUARY, etc.  Year is

	X     any year from 1900 to 9999.

	X

	X     4)  To  purge  all  old  appointments  leaving  only  current  month's

	X     appointments and future ones, please type:

	X

	X     $ VCAL/PURGE

	X

	X     5) To get help such as this one, just type:

	X

	X     $ HELP VCAL

	X

	X                                   Limitation

	X

	X     VCAL expects you to enter the hour in the format "hhhh".  If the  hour

	X     is not understood, say 2500, then it is set to 0000.

	X

	X     If you have several appointments scheduled for the same hour, you will

	X     be reminded for the first one only.

	X

	X                                User's Comments

	X

	X     To help us doing a good job  at  releasing  future  softwares,  please

	X     spend   a   few   minutes   of  your  times  answering  the  following

	X     questionaires and mail them to JAMES before March 30, 1987.

	X

	X     1) Do you gain any benefit from using this software?  Please clarify.

	X

	X     2) Do you find that the software is easy to use?  Please clarify.

	X

	X     3) In the next release of this software, what  features  do  you  want

	X     this software to have?

	X

	X     4) What area of Computer Science are you interested in the most?

	X

	X                                Acknowledgements

	X

	X     I would like to thank Mike Essex and those who did wrote  VCAL.   Only

	X     they  can  tell  the differences and enhancements.  Special thanks are

	X     pre-said to those who will response to the above questionaires.
