Runge-Kutta Method (Diff. Eq.)

Step Procedure                  Enter     Press     Display
------------------------------------------------------------

 1   Enter subroutine for f1              GTO A' 
                                          LRN

 2   Only 1 equation                      StFlg 1
     Second order Runge-Kutta             StFlg 2

 3   Enter desired step size     delta x  A         delta x 
     Enter x0                     x0      R/S       x0
     Enter y0(1)                  y0(1)   R/S       y0(1)
     Enter y0(2) if necessary     y0(2)   R/S       y0(2)

 4   Take integration step                B         x(j+1)
     Display y1(j+1)                      R/S       y1(j+1)
     Display y2(j+1)                      R/S       y2(j+1)

 5   Repeat for new
     integration step
