Or maybe I’m not used to doing it that way...

What do you mean by "store"?

You just type the data into the stack and let your program loose on it. For example, to calculate the volume of a sphere of height \(h\) and radius \(r\), \(v={\pi}r^2h\), you would enter \(h\) and then \(r\) onto the stack and run a program like this on them:

Code:

« → h r « r SQ π * h * →NUM » »

I mean what if you need to reuse these same data again within the program. If they’re stored (STO) you can recall them at will (RCL), still within the program.
Quite simple on a 41. Or maybe I don’t get the logic behind the 50g.
