User Memory and the Stack B-5
Disabling Operations
The five operations , /, -, () and
() 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 then entered writes over the X-register), but it enables stack lift when the
program resumes.
