Dieter,

However, the implementation is somewhat different and more powerful since you may define a function with multiple variables and tell the 42s solver for which one you want to have the equation solved.

The 35s can do all this just as well. But on top of this it also offers another feature: The function does not have to be programmed as a subroutine, you may also enter it directly as an equation in (well, close to) textbook syntax.

The 35s holds a list of equations that can be accessed and edited after pressing the EQN key. You may think of this as a separate memory space where more or less simple equations can be stored. They all may be evaluated, solved and integrated.
Thanks for your explanation. So the EQN list was kind of next evolutionary step in solving equations? Does that make the HP-42S MVAR commands obsolete in a calculator featuring EQN ?
