Thanks for the advice. I went to that link. It looks as though
one enters N equations (in as many unknowns, presumably as
"X_1, X_2, X_3...X_N") with all the known parameters, co-
efficients and unknowns all to the right of the = sign and being
set equal to zero (Eg: Y_1, Y_2...Y_N). Then the program
may find unique solutions, if any exist.

Is that more or less correct?
