Simple month calendar for CP/M
==============================

cal is a Unix-like cal(endar) utility for CP/M.

Usage
-----

    A> cal /s /h {month} {year}

Example
-------

    A> cal 2 2022
    February 2022
    Mo Tu We Th Fr Sa Su
        1  2  3  4  5  6 
     7  8  9 10 11 12 13 
    14 15 16 17 18 19 20 
    21 22 23 24 25 26 27 
    28 

Notes
-----

If the host has a supported real-time clock, the current month and year will be
used if these are not supplied on the command line. The value from the RTC can,
of course, be overridden on the command line.

A week is taken to start on Monday, unless /s is given, in which case it starts
on Sunday. 

The year must be a four-digit value. Year '23' is not 2023, but some time in
the Roman Empire.
