[TUHS] History of cal(1)?

[Jeff Johnson via TUHS]

You can also look at the code with (what should be) better indentation and proper syntax highlighting at https://dps8m.gitlab.io/sb/MR12.8/library_dir_dir/system_library_standard/source/bound_printing_cmds_.s.archive/calendar.pl1.html

THVV’s also allows adding custom text and holidays before printing and it also includes code for calculating the date of Easter.

It’s a quite the featureful program for when it was introduced.
