Thank you very much, Rob. Indeed the syntax of SOLVE can be confusing if you are used to the way it works on the 34C and 15C. These machines do not use lettered variables and simply use the stack for x as well as f(x). Thus here SOLVE is followed by the label defining the function instead of the variable: On a 34C the command SOLVE A solves the function programmed at label A, while the same command on a 35s solves a (separately declared) function for variable A. After I got the 35s this was a bit confusing for me either as I was used to the good old 34C.

I believe the 32S and 32SII (and maybe their algebraic bretheren) were similar to the 34C as well. The 34C is the first solver I learned eons ago, and like all first loves (actually 2nd after my 25C, but I digress) it is inherently correct.
