It's not every day we receive a LISP file that’s more than 20 years old, but this month we have one. Frequent contributor Raymond Rizkallah sends us a calendar creation routine he authored in 1993. It was recently tested in AutoCAD 2014 and still works fine. Load the LISP file, then type in the command YEAR. Verify the year and months you want to see, and it will create a calendar in your drawing using basic entities such as lines and text. Very neat, Raymond — thanks.
