X Pcal generates PostScript to produce landscape or portrait
X orientated calendars for any month and year. The defaults for
X month and year are the current month and year.
X
X VMS Version
X Execution format:
X
X pcal [options] [mm yy] [n]
X
X If a file named CALENDAR.DAT resides in the caller's home
X directory (or in a directory defined by the logical name PCAL_DIR,
X if it exists), it will be searched for lines with leading dates
X matching the requested month and year (current by default). Any
X text following the date will be printed on the calendar under the
X appropriate day of the month. Dates in the CALENDAR.DAT file may
X consist of a numeric or alpha month (at least the first 3
X characters for month names) followed by a numeric day and
X optionally followed by a year. Any non-numeric character may
X separate numeric dates. Holidays may be flagged by following the
X date immediately with '*'; this will cause the date to be printed
X in gray. Lines in the CALENDAR.DAT file consisting of "year xxxx"
X (where xxxx is a numeric year) can be used to set the year for
X following entries. This assumes that the following entries do not
X contain a year; any date entries containing year information will
X set the remembered year to that year. Lines consisting of
X "opt <options>" can be used to override defaults for all command-
X line flags except -e, -f, -D, and -U; any flags set in this manner
X are themselves overridden by flags specified explicitly on the
X command line. Comments ('#' through end-of-line) are permitted.
X
X Example:
X
X # sample CALENDAR.DAT file - Raytheon holidays and exempt paydays, 1990
X
X opt -t Helvetica-Bold -d Helvetica-Bold # override default fonts
X opt -M # print moon phase
X
X year 1990 # set default year
X
X 7/4* Independence Day # '*' flags 7/4 as holiday
X 7/12/90 Exempt payday # full numeric date
X Aug 16 Exempt payday # alternate date format
X 9/3* Labor Day
X 9/20 Exempt payday
X 10/8* Columbus Day (observed)
X 10/25 Exempt payday
X 11/20 Exempt payday
X 11/22* Thanksgiving
X 11/23*
X 12/13 Exempt payday
X 12/24*
X 12/25* Christmas
X
X Pcal supports rudimentary cpp-like functionality in the date file,
X supporting define | undef, if{n}def ... {else ...} endif, and
X include:
X
X define meetings
X
X ifdef meetings
X include meetings.dat
X undef meetings
X endif
X
X Symbol names are case-insensitive. It is not an error to "undef"
X an undefined symbol, nor to "define" a previously-defined one.
X
X "ifdef" alone is always false; "ifndef" alone is always true.
X
X The name of the file in the "include" directive may optionally be
X surrounded by either "" or <>, both of which are ignored. If the
X name is not an absolute path, it is taken to be relative to the
X directory where the file containing the directive is located.
X
X Pcal allows the user to print additional notes in an unused
X calendar box via lines of the form "note <month> <text>", where
X <month> specifies the month (numeric or alphabetic form) and
X <text> is the text to add. All such text will appear in the
X "Thursday" box on the last line (next to the small calendars).
X
X Pcal also looks for global symbol PCAL_OPTS; if defined, its
X contents are parsed as command-line flags. These override the
X program defaults, but are overridden by any specified via "opt"
X lines in the date file or on the command line. Example:
X
X $ define PCAL_OPTS "-n Helvetica -D meetings" ! login.com
X
X $ pcal -"U" meetings 9 90 ! un-define symbol at runtime
X
2 parameters
X mm yy n
X "mm" and "yy" are numeric values of the month (1-12) and year
X (0-99) (i.e., July 1990 would be 7 90). If you just include the
X "yy" option, an entire 12 months of calendars will be generated.
X A specific month can be produced by including the "mm" parameter.
X The "n" parameter will produce the "n" consecutive months of
X calendars starting with the requested month.
X
X The following flags may be specified (in increasing order of
X precedence) in global symbol PCAL_OPTS, in "opt" lines in the date
X file (all but -e, -f, -D, -U), or on the command line. Any flag
X which normally takes an argument may be specified without the
X argument; this resets its value to the program default. (-D
X alone thus clears all defined symbols; -U alone has no effect.)
X
X The '-' flag has been added to disambiguate cases where an
X argument-less flag has been specified immediately before a numeric
X parameter:
X
X $ pcal -t - 9 90
X
2 -e
X Print an empty calendar (i.e., do not print entries from a
X CALENDAR.DAT file.)
X
2 -f <FILE>
X Directs pcal to use the file name <FILE> as the input file in
X place of the default CALENDAR.DAT file in the callers home
X directory or in the directory specified by logical name PCAL_DIR.
X
2 -o <FILE>
X Directs pcal to write the PostScript calendar into FILE
X (default: CALENDAR.PS in the current directory.)
X
2 -l
X This will cause the output to come out in landscape mode
X (default).
X
2 -p
X This will cause the output to come out in portrait mode
X instead of landscape mode.
X
2 -b <DAY> | all
X This will cause all dates on weekday DAY to be printed in
X black; "-b all" causes all dates to be printed in black unless
X explicitly flagged as a holiday.
X
2 -g <DAY> | all
X This will cause all dates on weekday DAY to be printed in
X gray; "-g all" causes all dates to be printed in gray. Default is
X to print Saturdays and Sundays in gray and other dates in black.
X
2 -F <DAY>
X This will cause the weekday DAY to be the first day of each
X week; weekday DAY will appear in the left-most column of each
X calendar.
X
2 -t <FONT>
X This option can be used to change the font the title is
X printed in (ie. pcal -t Times-Roman). The default is Times-Bold.
X
2 -d <FONT>
X This option is the same as -t except that the font used to
X print the day numbers is changed. The default is Times-Bold.
X
2 -n <FONT>
X This option is the same as -n except that the font used to
X print the notes in the calendar boxes is changed. The default is
X Helvetica-Narrow.
X
2 -m
X This option causes a moon to be printed on days corresponding
X to a full, half, or new moon (default: no moons).
X
2 -"M"
X This option causes a moon to be printed on all days (default:
X no moons).
X
2 -"L" <STRING>
X This will cause STRING to be printed as a left footer.
X
2 -"C" <STRING>
X This will cause STRING to be printed as a center footer.
X
2 -"R" <STRING>
X This will cause STRING to be printed as a right footer.
X
2 -"D" <SYM>
X This will define symbol SYM prior to reading the date file;
X -D alone clears all defined symbols.
X
2 -"U" <SYM>
X This will undefine symbol SYM prior to reading the date file.

.SH DESCRIPTION
.I Pcal
generates PostScript to produce landscape or portrait calendars for any
month and year. The arguments
.BR month ,
.BR year ,
and
.BR nmonths ,
if provided, should be numeric. The
.BR month
value should be in the range 1 \- 12, and the
.BR year
value should be specified as 1 or 2 digits or as the full 4 digit year.
If no numeric arguments are provided, the calendar for the current month
and year will be generated.
.PP
If one numeric argument is provided, it is interpreted as the
.BR year
value, and calendars for the entire year will be generated. Otherwise,
.BR nmonth
months, starting with
.BR month
and
.BR year ,
will be generated.
.PP
If a file named
.I \.calendar
(or
.I calendar
for compatibility with older versions)
exists in the caller's home directory or in the directory pointed to by
environment variable
.BR PCAL_DIR ,
it will be searched for lines with
leading dates matching the requested month and year.
Any text following the dates found will be printed on the calendar under the
appropriate day of the month. Dates in the
.I \.calendar
file may consist of a numeric or alphabetic month (at least the first 3
characters for month names), followed by a numeric day and optionally followed
by a year. Any non-numeric character may separate numeric dates. Holidays may
be flagged by following the date immediately with `*'; this will cause the
date to be printed in gray.
.PP
Lines in the
.I \.calendar
file consisting of
.B year XXXX
(where
.B XXXX
is a numeric year) can be used
to set the year for following entries. This assumes that the following
entries do not contain a year; any date entries containing year information
will set the remembered year to that year.
.PP
Lines in the
.I \.calendar
file consisting of
.B opt <options>
can be used to override the defaults for
any command-line flags except
.BR \-e ,
.BR \-f ,
.BR \-D ", and"
.BR \-U .
Any flags specified in this manner
are, in turn, overridden by those specified explicitly on the command line.
.PP
Lines in the
.I \.calendar
file consisting of
.B note <month>
can be used to place notes regarding the
entire month is one of the unused blocks of the calendar. The
.B <month>
indicator may be either a number 1 through 12 or an alphabetic month name
as described above.
.PP
Comments are supported in the
.I \.calendar
file. Any characters following a `#' character through the end of the
line are ignored.
.PP
.I Pcal
supports rudimentary cpp-like functionality in the
date file, allowing the following constructs:
.BR "define | undef" ,
.B if{n}def ... {else ...} endif,
and
.BR include .
Note that these are not preceded by `#' as they are in C.
Symbol names defined using these keywords are case-insensitive.
It is not an error to
.BR undef
an undefined symbol, nor to
.BR define
a previously-defined one. An
.BR ifdef
alone is always false; an
.BR ifndef
alone is always true.
.PP
The name of the file in the
.BR include
directive may optionally be
surrounded by either "" or <>, both of which are ignored. If the
name is not an absolute path, it is taken to be relative to the
directory where the file containing the directive is located.
.I Pcal
is smart enough to translate
.B ~/
to the user's home directory.
.PP
.I Pcal
has many options:
.P
.TP 12
.B \-e
Prints an empty calendar. Do not print entries from a
.I \.calendar
file.
.TP
.BI \-f " cal"
Directs
.I pcal
to use the file name
.I cal
as the input file in place of the default
.I \.calendar
file in the user's home directory (or the directory pointed to by
.BR PCAL_DIR ).
.TP
.BI \-o " file"
Directs
.I pcal
to write the output to
.I file
instead of to stdout.
.TP
.B \-l
Causes the output to be in landscape mode (default).
.TP
.B \-p
Causes the output to be in portrait mode.
.TP
.B \-m
Causes moon icons to be printed on dates corresponding to
new, half, and full moons (the default is that no moons are printed).
.TP
.B \-M
Causes moon icons to be printed on all dates (the default is
that no moons are printed).
.TP
.BI \-b " day" " | all"
Causes all dates falling on weekday
.I day
to be printed in black;
.B \-b all
causes all weekdays to be printed in black.
.TP
.BI \-g " day" " | all"
Causes all dates falling on weekday
.I day
to be printed in gray;
.B \-g all
causes all weekdays to be printed in gray.
.IP
The default for the
.BR \-b " and " \-g
flags is to print Saturdays and Sundays in gray and other days, unless
flagged as holidays, in black.
.TP
.BI \-F " day"
Selects weekday
.I day
as the first day of the week. The given day will appear in the left-most
column of the calendar.
.TP
.BI \-t " title_font"
Sepcoifies the name of a font to use to print the
month name and year at the top of the calendar. For example,
.BR "pcal \-t Times-Roman" .
.TP
.BI \-d " day_font"
Similar to the
.B \-t
option, but selects the font used to print the day numbers.
.TP
.BI \-n " text_font"
Similar to the
.B \-t
option, but selects the font used to print the text inside each day and in
the notes block.
.TP
.BI \-D " symbol"
Defines the named symbol prior to reading the date file.
.TP
.BI \-U " symbol"
Un-defines the named symbol prior to reading the date file.
.TP
.BI \-L " string"
Causes the accompanying string to be printed as a left-justified footer.
.TP
.BI \-C " string"
Causes the accompanying string to be printed as a centered footer.
.TP
.BI \-R " string"
Causes the accompanying string to be printed as a right-justified
footer.
.PP
Any option which normally takes an argument may be specified without
the argument in order to reset the value to the program default. Note that
while the
.B \-D
option alone clears all the defined symbols, the
.B \-U
option alone has no effect. The
.B \-
(or
.BR "\- \-" ,
System V people)
flag may be used to disambiguate command lines such as:
.IP
.B pcal \-t 9 90
.PP
This could be written instead as one of the following:
.IP
.B pcal \-t \- 9 90
.br
.B pcal \-t \- \- 9 90
.PP
If the environment variable
.BR PCAL_OPTS
is defined, its contents are parsed as a command line. Flags set via
.BR PCAL_OPTS
override the program defaults, but are overridden by flags set via
.B opt
lines in the
.I \.calendar
file or explicitly on the command line.
