(35s) Double Deck Descriptor: A 2-level Description of Input

[Gerald H]

Double Deck Descriptor

I now present the DDD for the HP 35s.

For input

0
22367899

the programme returns

211112
987632

to be read as

291817161322

to be read as

two 9s one 8 one 7 one 6 one 3 two 2s.

Limitations: No particular digit may appear more than 9 times in the combination of the two levels - results become incoherent.

The initial zero on stack level Y is needed as a starter - indeed, it could be replaced by any number, but the result would be questionable.

If the programme is now again activated, you get a description of

291817161322

& so on.

You may notice the awkwardness I have in dealing with indirect addressing of variables - I would be grateful for improvements.

I have used (I) to represent indirect I as the sign occurs where ordinary brackets are not allowed.
