Integers 0 - 100 only consume 1.5 bytes of memory for the original HP 32S and the range is extended to 0 - 254 for the HP 32SII.
I didn't remember that the range was up to 254 for the 32SII. That's perfectly correct of course. Thanks for reminding us.

The 32S/32SII have so little memory that using numeric constants (other than the 0..99 or 0..254) in a program must be avoided. For instance, it is much better to do 12 +/- rather than -12). To enter large constants (e.g. 1000), we have better to do for instance 10 ENTER x^2 * or if speed is not a concern 3 10^x.

In this sunny sunday mornig, I was posting this message when by rereading it, a shorter and simpliest version pop up in my awaking brain that use a MOD instruction :

Code:
01 LBL "SQYX2"
02 ENTER^  SQRT  INT  MOD  LSTX
06 END
Unfortunately, the 32S/32SII lack the MOD function.
