100 Appendix B: Classes of Operations
Neutral Operations
Many operations are neutral—they do not alter the previous status
of the stack lift, whether enabled or disabled.
The following operations are neutral with regard to stack lift.*
HEX MEM PSE
DEC <], R/S
ocT (GTO](-)nnn CLEAR
P/R CLEAR BST
SHOW {(HEX], [DEC], [OCT], [BINJ}
SET COMPL {[1's],[2's], [UNSGN]}
(when in Floating Point mode)
Enabling Operations
Most calculator operations are stack lift-enabling. A number keyed
in after one of these operations will lift the stack (because the stack
has been “enabled’ to lift).
All operations not listed above as disabling or neutral are
enabling.
Operations Affecting the LAST X Register
The following operations save x in the LAST X register:
)
NOT ASR RRC
[x]) [DBL:] (CHS] T
(¢] [DBLR] [AND RLn
Executing the function from Integer mode clears the
LAST X register.
* Also: the digit entry operations are neutral before termination of digit entry.
T In Integer mode.
