34S Mini-Challenge : A to Z

[Nick]

Here's a compressed menu/scan routine for converting key scan codes for A-Z to 1-26 and all others to negative values (for demo display) in 39 steps. This includes a full set of labels (1 for A-Z as a group, and 1 each for the other keys; Y and EXIT are excluded by firmware) for the user to insert their code:

The challenge is can this demo/routine be compressed further?

Yip,
