Tripartite Palindromic Partition of Integer (HP 50g) Challenge

Hi 3298,

Attached is an updated set of User RPL programs that use the algorithms in the paper for all numbers including those with 2-6 digits (in SML2-SML6). I've tested all numbers exhaustively up to 199999 so there are no bugs in the code specific to the 2-6 digit cases. Algo2 has been modified to handle the callback from SML6 for numbers that don't begin with 1 in case the 6-digit no. is a "special" number (case II.2.ii.c). I have not tested exhaustively beyond 200000 since I am running the code on a physical 50g and it takes a long time to do so.

I am very curious to see how much smaller / faster your SysRPL version turns out to be. I have been trying to learn SysRPL but it has been pretty heavy going so far.

Attachment removed since there was an additional case that was not covered by the paper I was referring to - the fixed code (as per the later version of the paper) is attached to a later post
