(12-15-2021 10:02 PM)J-F Garnier Wrote: ENTER on the ΣXY sum register seems to recall the value of A (or 0 if non existing) on the stack. OK, the explanation was not too difficult to identify. This is the same root cause, the routine that is managing ENTER in the MEM/VAR menu shares the code managing the "RCL var" command, and the "var" argument is extracted from the command code by masking with 31 (0x1F), giving a range from 0 to 31 for the A..Z, i and (i) parameters. But now with ENTER in MEM/VAR, the ΣY2, ΣXY sum registers have codes 32 and 33 (dec), giving 0 and 1 after masking. Code 1 corresponds to the variable A, but code 0 is not defined and the 32SII considers it as an non-existing variable and returns 0.
