But your suggestion is certainly valid for a calculator with roll-up and those that need or want the upper registers filled with the initial x.

I find this feature very handy, so much I don't mind spending one extra step on the regular HP-12C:

Code:


01 f RND            001 f RND
02   Rv             002   Rv
03   ENTER          003   ENTER
04   ENTER          004 g LSTx
05 g LSTx           005   /
06   /              006 g LSTx
07 g LST            007   x<>y
08   x<>y           008 g INTG
09 g INTG           009   *
10   *              010   -
11   -              011 g GTO 000
12 g GTO 00
