34S Mini-Challenge : A to Z

[Nick]

Printing Word Processor (It's not my typewriter, but it does print stuff...)

Usage:

f, g, h are all [Shift] with = as the annunciator (Flag A)
A-Z appends a character
[Shift]A-Z appends a lowercase character
ENTER will Print + Clear
[Shift]ENTER will Print (without Clear)
<- will Backspace
[Shift]<- will Clear
0 is Space
Y is forgotten

Comments:

- There's room to tweak when the shift keys clear or not.
- Other annunciators such as 360/GRAD could be used for additional Shift keys.
- Numerics / punctuation could be added.
- Bold / Underline / Mode 1 / Mode 2 could be added.
- The 82240A font could be selected if you're using an 82240B.
- A blinking ViewA could be used to render a cursor for text editing.
- CPX could simplify every operation.
- The forgotten Y key could be asked for forgiveness.

Inspiration:

- Special thanks to Someone Special who's Someone other than Someone, Pauli, the Daleks, and these words from the 3.1 manual: "Nevertheless, do not forget that your WP 34S is mainly designed as a programmable calculator."
