X            VCAL AND FRIENDS                  1/29/87
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
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.TH VCAL 1
X.SH NAME
Xvcal \- visual calendar and notes program
X.SH SYNOPSIS
X.B vcal
X[ month year ] [ filename ]
X.sp
Xwhere
X.I month
Xis a numeric value between 1 and 12,
X.I year
Xis a numeric four digit value and
X.I filename
Xis the data file to be accessed.
X.SH DESCRIPTION
X.I Vcal
Xis a visual calendar program which allows the user to enter notes
Xand appointments for each day of the month.  It can be used to
Xreplace the "paper" desk or wall calendar with an electronic one
Xwhich can be accessed from any terminal or modem connected to the
Xcomputer system.
X.PP
XWhen a date argument is present,
X.I vcal
Xwill display the requested month and year.  The default argument values
Xare the current month and year.  When a filename argument is used
X.I vcal
Xwill uses that file instead of the default ~/.appointments file.
XIf ~/.appointments is not used the filename of the current file
Xwill appear at the top of the
X.I vcal
Xcalendar.
X.SH OPERATION
X.I Vcal
Xis entered from UNIX by typing the
Xcommand followed by an optional month and year value.  A calendar
Xwill be displayed on the screen with the cursor located on the first
Xday of the month.  The cursor may be moved to different days
Xin the following manner.
X.br
X.sp
X.nf
Xkey             function
X---             --------
Xj               move cursor down
Xk               move cursor up
Xl               move cursor to the next day
Xh               move cursor to the previous day
Xb               move cursor to the beginning of the month
Xe               move cursor to the end of the month
X.sp
X.fi
X.PP
XPrevious and following months may also be accessed.
X.br
X.sp
X.nf
Xkey             function
X---             --------
Xp               previous month
Xn               next month
X.sp
X.fi
X.PP
XUp to eighteen appointments may be entered on each day of the month.
XThese may be displayed, modified or cleared in with the following keys.
XThey will operate on the day selected by the current cursor position.
X.br
X.sp 4
X.nf
Xkey             function
X---             --------
Xspace           display appointments for the selected day
Xm               enter or modify appointments
Xc               clear all appointments for the selected day
X.sp
X.fi
X.PP
XWhen the 'm' is pressed
X.I vcal
Xenters notes mode.  While in this mode notes may be added, modified,
Xdeleted, yanked or put.
X.br
X.sp
X.nf
Xkey             function
X---             --------
Xj               move cursor down
Xk               move cursor up
Xi               begin data insertion
XESC/CR          end data insertion (only while in insert)
Xd               delete the selected line
Xy               hold the current line
Xp               insert the held message
XCR              exit notes mode and return to the calendar
X.sp
X.fi
XData must begin with the appointment time in 24 hour format
X(no ':' should be used).  Entering new data will erase the current
Xmessage on that line.  A held line will be available to insert until
Xit is changed or the user exits
X.I vcal.
XA line which is deleted using the 'd' key will be placed in the hold
Xbuffer.
X.PP
XWhen the cursor is on the calendar a carriage return will cause the
Xthe appointment data to be saved and
X.I vcal
Xto exit.  Break or delete will cause
X.I vcal
Xto exit without updating the ~/.appointments file.
X.PP
XA 'H' will display help messages.  A calendar help message
Xwill be printed when
Xthe cursor is on calendar days.  A notes help message
Xis printed when the cursor is in the notes area.
X.PP
XFive companion programs are available to use with the
X.I vcal
Xprogram.  These are:
X.br
X.sp
X.nf
Xappts           display current or selected days appointments
Xeappts          enter appointments from the UNIX command line
Xautocall        set appointment reminders for the current day
Xlcal            displays month's appointments in tabular form
Xcallme          sets appointment reminders
X.fi
X.sp
XFor further information on these, reference the appropriate "man"

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:    vcal.c
X *
X * Purpose:    visual appointment calendar
X *
X * Author:    Mike Essex
X *
X * Date:    Sep. 16, 1986
X *
X * Includes:
X *    time.h, stdio.h, ctype.h, signal.h
X *
X * Discussion:
X *    displays a calendar to the screen for the current or optionally
X *    specified month.  User may move the cursor any day of the month
X *    and view or enter appointments for that date.
X *
X *
X * Edit History
X * ==== =======
X *
X * Date      Who    What
X * ----      ---    ----------------------------------------------
X *11/25/86   me         added multiple data file capability
X *11/25/86   me         fixed array "home" from *home[80] to home[80]
X *11/25/86   me         fixed "space" and "area" to be global
X *11/26/86   me        changed help message routines
X * 2/06/86   me        changed calendar header from printing a default
X *            NULL for .appointments file to not printing
X *02/19/86   me        reworked terminal handler to make correct use
X *            of termcap(3) functions for greater terminal
X *            portability.  modified so that cursor comes to
X *            current day of month on startup.  Fixed minor
X *                      bugs and changed a few messages.

X.TH VCAL 1
X.SH NAME
Xvcal \- visual calendar and notes program
X.SH SYNOPSIS
X.B vcal
X[ month year ] [ filename ]
X.sp
Xwhere
X.I month
Xis a numeric value between 1 and 12,
X.I year
Xis a numeric four digit value and
X.I filename
Xis the data file to be accessed.
X.SH DESCRIPTION
X.I Vcal
Xis a visual calendar program which allows the user to enter notes
Xand appointments for each day of the month.  It can be used to
Xreplace the "paper" desk or wall calendar with an electronic one
Xwhich can be accessed from any terminal or modem connected to the
Xcomputer system.
X.PP
XWhen a date argument is present,
X.I vcal
Xwill display the requested month and year.  The default argument values
Xare the current month and year.  When a filename argument is used
X.I vcal
Xwill uses that file instead of the default ~/.appointments file.
XIf ~/.appointments is not used the filename of the current file
Xwill appear at the top of the
X.I vcal
Xcalendar.
X.SH OPERATION
X.I Vcal
Xis entered from UNIX by typing the
Xcommand followed by an optional month and year value.  A calendar
Xwill be displayed on the screen with the cursor located on the first
Xday of the month.  The cursor may be moved to different days
Xin the following manner.
X.br
X.sp
X.nf
Xkey             function
X---             --------
Xj               move cursor down
Xk               move cursor up
Xl               move cursor to the next day
Xh               move cursor to the previous day
Xb               move cursor to the beginning of the month
Xe               move cursor to the end of the month
X.sp
X.fi
X.PP
XPrevious and following months may also be accessed.
X.br
X.sp
X.nf
Xkey             function
X---             --------
Xp               previous month
Xn               next month
X.sp
X.fi
X.PP
XUp to eighteen appointments may be entered on each day of the month.
XThese may be displayed, modified or cleared in with the following keys.
XThey will operate on the day selected by the current cursor position.
X.br
X.sp 4
X.nf
Xkey             function
X---             --------
Xspace           display appointments for the selected day
Xm               enter or modify appointments
Xc               clear all appointments for the selected day
X.sp
X.fi
X.PP
XWhen the 'm' is pressed
X.I vcal
Xenters notes mode.  While in this mode notes may be added, modified,
Xdeleted, yanked or put.
X.br
X.sp
X.nf
Xkey             function
X---             --------
Xj               move cursor down
Xk               move cursor up
Xi               begin data insertion
XESC/CR          end data insertion (only while in insert)
Xd               delete the selected line
Xy               hold the current line
Xp               insert the held message
XCR              exit notes mode and return to the calendar
X.sp
X.fi
XData must begin with the appointment time in 24 hour format
X(no ':' should be used).  Entering new data will erase the current
Xmessage on that line.  A held line will be available to insert until
Xit is changed or the user exits
X.I vcal.
XA line which is deleted using the 'd' key will be placed in the hold
Xbuffer.
X.PP
XWhen the cursor is on the calendar a carriage return will cause the
Xthe appointment data to be saved and
X.I vcal
Xto exit.  Break or delete will cause
X.I vcal
Xto exit without updating the ~/.appointments file.
X.PP
XA 'H' will display help messages.  A calendar help message
Xwill be printed when
Xthe cursor is on calendar days.  A notes help message
Xis printed when the cursor is in the notes area.
X.PP
XFive companion programs are available to use with the
X.I vcal
Xprogram.  These are:
X.br
X.sp
X.nf
Xappts           display current or selected days appointments
Xeappts          enter appointments from the UNIX command line
Xautocall        set appointment reminders for the current day
Xlcal            displays month's appointments in tabular form
Xcallme          sets appointment reminders
X.fi
X.sp
XFor further information on these, reference the appropriate "man"
Xentries.
