HP-35s Programming

[Dave Britten]

I haven't done any 35S programming in a while, but I believe you press RCL before each key to put a letter into freeform text. A little clumsy, but you probably won't be entering enormous messages on this model anyway.

For your second question, I think the INPUT command might do what you're interested in. This behaves sort of like VIEW, but it also puts the variable into the X register, and when you press R/S, it places the new X register contents back into the variable (or you can just press R/S without entering/calculating anything to keep the current value).
