Before you run the program, you need a 30x4 matrix stored in the variable UFLG. The first column should contain 0 through 10 and 81 through 99. This is an index for the user flags. The rest of the matrix can be 0s when you start.

How It Works

When you run UFLG it'll display a flag number followed by a ":" and then a note up to 18 characters long that you've supplied about that flag's purpose. Here's a Free42 screen capture to give you an idea:

- The up and down arrows scroll through the list of flags.
- Key 1 toggles the set/clear state of the current flag. If a square appears before the flag number, it means the flag is currently set.
- Key 6 opens the alpha register so you can add or change the note for the current flag. To fit on a single line (and in the 30x4 UFLG matrix) your note cannot be longer than 18 characters. It is possible that if you add 5 more columns to your UFLG matrix you'll be able to use both lines of the alpha register, but I've not tested that yet.
- Exit key ends the program and returns both the stack and the alpha register back to the state it was in before you ran UFLG.

- Shift key 1 clears all user flags.
- Shift key 6 clears your note for the current flag.

Here's the program!
