Hi
I was wondering if someone could send me or post a simple program that would
take a matrix on the stack eg [[ 2 3 4 5] or any arbitrary size and return the
square of all of the elements [ 3 1 3 4] in the array . It sounds trivial but
the manual is not clear on [ 2 3 1 1] this aspect of programming the 48sx,
thanks in advance. [ 1 3 3 1]]

This can be done more efficiently, and robustly (especially with the internal system rpl), but the above will at least set you in the right direction. Enjoy, -JimC -- James H.
