A is the return address. The address may be indexed, indirect or extended. When not extended, the final address controller bits specify the most significant digit of the address. This permits branching to any address up to and including 299,998, relative to Base #1, without indexing or extension. When the address is indexed, the final Base Indicant should resolve to a value of 1. The processor will always treat the resolved address as being relative to Base #1. The processor will not check for improper memory assignments. The normal return address is obtained by setting the A address to zero, indexing by IX3 and settting the address controller to indirect. When the address is indexed by IX3, the initial contents of IX3 are used.
The Exit instruction reverses the actions of the Enter instruction, thus accomplishing an exit from the stack.
The instruction restores the settings of the Overflow and Comparison flags as specified by IX3 plus 15 if the digit at IX3 plus 14 is zero. if the digit at IX3 plus 14 contains a one, the flags will not be restored. All other values are reserved.
Copy the least significant six digits contained in IX3 to memory location 000040 relative to Base #0.
Copy the eight digits at the location specified by IX3 plus 6 to IX3.
There are no overlap restrictions for this instruction.
