Don and I have been poking around the 17bii+, trying to determine if any of the bugs listed in older versions still exist, and well, trying to get used to the solver. ;-)

First, there are a couple threads in Forum Archive 14...

...which talk about bugs in the early 17bii+ units. I've tried a few of these and they all work correctly, as expected, on my version. For the record, my S/N is CNA 63401403.

Also, Don and I have been trading implementations for summing up the digits of a number (i.e., 123 = 1+2+3 = 6). Here is the version that ultimately worked:

SOD:SUM=0xL(B:A)+sigma(I:1:LOG(A)+1:1:MOD(B:10)+0xL(B:IP(B/10)))

Don also has a version which uses the statistical lists to get the sum, assuming each digit is in a list (L1) item:

sod:sum=sigma(i:1:sizes(L1):1:Item(L1,i))

As we work through more, I may post some follow-ups. It's good to see that some of the ugly bugs have been fixed. Hopefully they're all good!

thanks,
