For all of the programs except NEWTON and BROY, you should link the object file
by selecting "Y" below.  This step forms the compiled version of the program.

To use NEWTON, you must edit the subroutine FUNC.SUB each time you want to
solve a new set of equations.  Compile NEWTON.FOR separately from FUNC.SUB
so that each time you change the equations, you only have to compile FUNC.SUB
again.  Compile the two routines as explained earlier, but do not link
them (select "N" below).  After both are compiled, link them together by
typing the following command:

LINK <file 1> <file 2> . . .  /* Don't put extensions in the file names */

For example:  LINK NEWTON FUNC

This command will form a compiled version of NEWTON that contains FUNC.SUB.
When you change the equations, compile only FUNC.SUB and perform the link.

Similiarly, to use BROY, you must edit BROY.FOR each time you want to solve
a new set of equations.  Compile BROY.FOR and its subroutine MINI.SUB
separately, but do not link them.  After both are compiled, link them together
by using the LINK command explained above.  When you change equations
compile only BROY.FOR and perform the link.
