Whenever I put 'a' 'b' 'c' on the stack (small letters). The numbers 1, -1, -1 appear on the stack, after keying ENTER.

How can I get small letters on the stack?

Did I save numbers for these small letters in the stack? How did I do this?

Try the VAR key. See that menu label that looks like [ a ]? That's your 'a' variable. Yes, you (or a program you ran) created it. If you want to put 'a' on the stack without evaluating it, just type it inside single quotes. That's what the ['] key is for: entering variable names without executing them.

Did you read the section in your manual about variables? If not, please do. (This is known as a "preemptive strike").
