X            VCAL AND FRIENDS                  2/19/87
X
X-------------------------------------------------------------------
XThis is the second release of vcal and friends.
XIt has fixed a number of problems and incorporated some suggestions
XI recieved in your responses.  For the most part I have received
Xenthusiastic replies and I thank you for the responses.  There
Xwere a number of sites who didn't recieve both pieces and some
Xwho had pieces truncated.  Hopefully, this release will get through
Xto all.
X
XChanges include:
X
Xvcal - Changed terminal handler routines to take advantage of
X       termcap(3) capabilites allow vcal to be used with a greater
X       number of terminal types.  Changed start up cursor position
X       to current date.  Fixed several minor bugs.
X
Xautocall - Fixed a loop bug which was causing core dumps in some
X       instances.  Changed message buffer size.
X
Xcallme - No change.
X
Xappts.c - Changed message size so that long messages from a manually
X          edited data file does not cause a core dump.
X
Xeappts - Changed message buffer size.
X
Xlcal - Changed message buffer size.
X-------------------------------------------------------------------
Xdef.:  a set of calendar and appointment utility programs to replace
X       the traditional paper calendar.
X
XVcal and friends allow the user to view a calendar, enter dates and
Xtimes of activities, set times for prompts to the CRT and to produce
Xlists of a month's activities.  Multiple data files may be used to
Xallow the user to have one calendar for personal activities, one for
Xbusiness activities, one for project milestones, etc.
X
XThese programs are written in 'C' and run under UNIX.  To date they
Xhave been compiled and execute on the following systems:
X
XDEC PDP 11/70    UNIX Version 7
XDEC VAX 11/750    UNIX BSD 4.2 and 4.3
XSun 2/170    UNIX BSD 4.2
XSun 3/160    UNIX BSD 4.2
XSun 3/260     UNIX BSD 4.2
XDEC MicroVAX    ULTRIX
X
XIncluded in this package are six source files, six manual files, a
Xmakefile and this introduction.  The makefile is for use with the
Xstandard "make" utility on a VAX 11/750 under BSD 4.3.  For use with
Xa PDP 11/70 BSD Version 7 change the makefile library entry from
X"termlib" to "termcap".
X
XAll the "vcal" files have been combined here with the "shar" script.
XSince the combined size of the files are greater than 65,000
Xcharacters they have been broken into two parts for transmission.
XPart 1 contains makefile, appts.c, autocall.c and callme.c along
Xwith the manual pages for these.  Part 2 contains eappts.c, lcal.c
Xand vcal.c and their manual pages.
X
XSynopsis of files:
X
Xappts        displays the current or specified day's activities
X
Xautocall    starts background reminder processes for each of the
X        current day's activities
X
Xcallme        starts a background reminder process for a specified
X        time and activity
X
Xeappts        allows activities to be entered into a data file from
X        the command line
X
Xlcal        produces a tabular listing of the current or specified
X        month's activities
X
Xvcal        visual calendar displaying the current or specified
X        month's activities; allows entries to be added, changed
X        or deleted
X
Xmakefile    makefile for all of the "vcal" programs
X
Xmanual pages:    appts.l autocall.l callme.l eappts.l lcal.l vcal.l
X
XComments and suggestions will be appreciated and considered.

X * Module:    appts.c
X *
X * Purpose:    Displays current or specified date's appointments
X *
X * Author:    Mike Essex
X *
X * Date:    Sep. 16, 1986
X *
X * Includes:
X *    time.h, stdio.h, ctype.h
X *
X * Discussion:
X *    This program reads a designated data file or, by default,
X *    the .appointments file in the user's home directory and
X *    displays the current days appointments if no command line
X *    arguement is given.  An optional numeric month, day and
X *    year arguement may be specified to display appointments
X *    for a different day.  Output is standard out.

X.SH NAME
Xappts \- display current or selected day's appointments
X.SH SYNOPSIS
X.B appts
X[ month day year ] [ filename(s) ]
X.sp
Xwhere
X.I        month
Xis a numeric value between 1 and 12,
X.I        day
Xis a numeric value between 1 and 31,
X.I        year
Xis a numeric four digit value and
X.I        filename(s)
Xis the name of the data file(s) to access.
X.SH DESCRIPTION
X.I Appts
Xis a program which uses the data stored by "vcal" or "eappts" to
Xdisplay the user's appointments to standard out.
X.PP
XWhen a date argument is present,
X.I appts
Xwill display appointments for the requested month, day and year.
XThe default argument values are the current month, day and year.
XWhen one or more filename arguments are used,
Xthose data files will be searched.
X.PP
XFive companion programs are available to use with the
X.I appts
Xprogram.  These are:
X.br
X.sp
X.nf
Xvcal            calendar and notes program
Xeappts          enter appointments from the UNIX command line
Xautocall        set appointment reminders for the current day
Xlcal            displays month's appointments in tablular form
Xcallme          sets a reminder prompt
X.fi
X.sp
XFor further information on these, reference the appropriate "man"
Xentries.
