I wound up redoing the transliteration I'd been working on, and have about 3/4 of the code ready for optimization and final rewrite.

What remains may leave me bald by the time I finish.

I do now see that I will have to have at least four arrays - two based on constant tables that were in the original ROM (one 19-character x 1 row and the varLoad table of constants - I've defined it as a 26 x 5 array), one (maybe two) for the 8-digit numeric readout, and one for a specific section of RAM as there are multiple operations involved using the index register.
