Unofficial Name: GetRestrictionsOptions

BCALL Address: 531D

Minimum OS Version: 2.40

Displays configuration screen for Press-to-Test and returns the user's choice.


  • Carry flag: set for delete menu, reset for disable menu


  • Z set if user canceled with [2nd]+[QUIT]/[CLEAR]/etc., reset if OK selected
  • B: bit 0 reset for radians, set for degrees
  • B: bit 1 reset for stat diagnostics OFF, set for ON



This clears the screen, sets up the homescreen context, and empties the edit buffer.

This is only intended to be used with applications, not RAM programs. It is also the only BCALL to use the carry flag as input.
