newRPL - build 1255 released! [updated to 1299]

I forgot to mention, MSOLVE also accepts a program instead of a list of equations. The program must take N arguments from the stack (N=number of variables provided in the list of variable names) and return a single real number. The algorithm will try to minimize the result of the program.
A program that does the sums of the squares of various expressions would be equivalent to providing the list of expressions directly.
