There is no SIZE? command in this calculator.

Very simple. Start RCL-ing from maximum possible register number down. Depending on how much memory is available will take you less than a minute to figure it out.

:-) :-) good joke, thank you, I know that way of course.
Less than a minute? Even if you have quad memory installed?
