Worksheet is a basic spreadsheet program.

This is a tricky one.

Paint opens up files like this, using a variety of different modes. It supports more than the 4-color limit of the Tandy, it seems.
However unless you happen to have a Tandy keyboard or a Tandy keymap it is impossible to exit!

The Calendar is a basic agenda program.

Of course Personal Deskmate 2 supports printing. Printing is the most important thing on the computer save knowing how to use it and making documents.
Apparently it is capable of printing non-ASCII text as well.

Arguably the most interesting program of the bunch is Filer, which allows you to create forms and input data.
