HP 35s User Manual

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.

DEG, RAD,
