sliding count jumps Another type of jump is called a count jump. A count jump lefts the calculator to add or subtract one to a memory. Then if the value contained by the memory is not zero the calculator should proceed to the next sequential program statement. If the value contained by the memory is zero, then the calculator should skip the next statement. There are two types of count jumps: Incrementalist and skip on zero *This count jump increments the memory.

® What are Branches and Subroutines? A common technique when programming a calculator is known as branching. With branching, you instruct the calculator to go (branch off} from one programmed cab osculation to another, The original programmed calculation from which you branched is called the main routing, while the destination is called the subroutine. Generally, processes (routines) that are repeated often are put into subroutines and branched to when they are necessary.
