33s repeated operations
Message #1 Posted by Sam Levy on 12 Mar 2007, 1:52 p.m.

I am used to the RPN stack and often use the repeating t register to stream down a constant. For example the multiplication of a series by 2. I found in the algebraic mode if I keyed 2 X 2 enter, it of coursr gave 4. I entered again, it put the X number in Y and gave me the answer 8. It can be repeated.

I think this a called 'constant mode' or an extended version of it. The idea is really old :-).

I remember the old TI's having this feature back in the 70's.
