PARAMETERS
       A single parameter specifies the year (1 - 9999) to be displayed;  note
       the  year  must  be fully specified: cal 89 will not display a calendar
       for 1989.
       Two parameters denote the month (1 - 12) and year.
       Three parameters denote the day (1-31), month and  year,  and  the  day
       will  be  highlighted if the calendar is displayed on a terminal. If no
       parameters are specified, the current month's calendar is displayed.
       A year starts on Jan 1. The first day of the week is determined by  the
       locale.
       The  Gregorian  Reformation  is assumed to have occurred in 1752 on the
       3rd of September. By this time, most countries had recognized the  ref-
       ormation  (although a few did not recognize it until the early 1900's).
       Ten days following that date were eliminated by the reformation, so the
       calendar for that month is a bit unusual.
