Re: HP-20S:How do I store memory?(i have no manual) Message #2 Posted by J. Lopez on 6 July 2001, 9:44 p.m., in response to message #1 by cam
The HP-20S has ten storage registers R0 thru R9. They're accessed via the STO and RCL keys. If you wanna save the number in the display into register 3, for example, you'd press STO followed by 3. The number in the display will be stored in register R3, without being dropped.
The recall function is, likewise, straightforward: press RCL followed by the one-digit register number.
To cancel STO or RCL after having pressed the keys, press the C (ON key) or the Backspace.
Hope this helps.
