All functions except those in the following two lists will enable stack lift.
Disabling Operations
The four operations ENTER,
Σ
+,
Σ
–, and CLx disable stack lift. A number
keyed in after one of these disabling operations writes over the number
currently in the X–register. The Y–, Z– and T–registers remain unchanged.
In addition, when
and
@
act like CLx, they also disable stack lift.
The INPUT function disables stack lift as it halts a program for prompting (so
any number you then enter writes over the X–register), but it enables stack lift
when the program resumes.
