Jump Operations
The Jump operation directs the computer to depart from the normal sequence of step-by-step
instructions and jump to a pre-selected point in the program.
These instructions provide both internal and external (manual) decision capability and are
useful to:
Create "loops" that allow repetitive sequences in a program to be executed.
Select alternate routines or subroutines at the discretion of the operator.
Automatically "branch" to alternate routines or subroutines according to the value
in the "A" register.
The jump operation requires two related instructions:
1. Point of origin: where to start the jump, Interrupting the sequence.
2. Reference point: where the jump will arrive, restarting the sequence.
There are two types of jump instructions:
Unconditional jumps
Conditional Jumps
