number base conversion for hp17b/17bii

[Thomas Klemm]

But then I realized that the 1:1 translation of my HP-11C program was shorter. And it uses only 3 registers. However it was fun to figure it out.

Addendum:
As long as the from-base PMT doesn't change the following lines could be removed:

Code:

15 -        1  1
16 -    45 14  RCL PMT
17 -       22  1/x
18 -       24  Δ%
19 -    44 12  STO i
20 -       33  R↓
21 -       33  R↓

With this we are at the same number of lines.
Of course you still have to calculate i once and store it.

I've seen this trick in Valentin's paper: HP-12C’s Serendipitous Solver
