Cal
Cal is a little program I wrote when I needed it for a demo. Is is quite similar to the Unix command cal. It displays a simple calendar.
Synopsis
cal [-13msyeh?] [[month] year]
Options:
| -1 | Print one month only (default). |
| -3 | Print the previous month, the month and the next month on one row. |
| -m | Print a calendar where Monday is the first day of the week, as opposed to Sunday. |
| -s | Print a calendar where Sunday is the first day of the week (default). |
| -y | Display a calendar for the entire year. |
| -e | Use English month and day names. Cal will otherwise use the local month and day names. |
| -h, -? | Display a simple help screen. |
A single parameter specifies the year (1 - 9999) to be displayed. The year must be fully specified: "cal 89" will not display a calendar for 1989 or 2089. Two parameters denote the month and year. The month is a number between 1 and 12.
A year starts on January 1.
Compilation
Compilation is straighforward.
An older version required my Console unit, but that posed problems when text was redirected to a text file or some other stream (IOW, there is a bug in Console I could not correct yet). Since Console was only used to reverse colours for the display of the current date, I used direct Windows API calls to achieve this, in the new ReverseColors procedure.

I hope this code is useful to you. If you use some of it, please credit me. If you modify or improve the program, please send me the modifications.
I may improve or enhance Cal myself, and I will try to post changes here. But this is not a promise. Please don't request features.
