RE: 48G-50G Runge-Kutta Diff Eqn solver
Thank you, Werner, for your comment.

Could you provide some clarifications? What do \ and @ in your Code mean or do? I don't see them in any programs in the Advanced User Reference. If I key your suggested procedure (between the guillemets) nothing is saved from the @ on. Is [y v] the input to the procedure? ( 2 GET . . .) And, ARRY the return? How is the procedure called? It can't be substituted in the solution vector [y v].

I made a mistake in my question: should be y' = G - K * v^2 (* looked too small for legibility, so I used X). G = 9.8 and K = 0.005. So, y' = 9.8 - 0.005 * v^2.

Thanks for any help.
