Prerequisites[edit]
Repeat-While Loop[edit]
A repeat-while loop (which is also sometimes called a do-while loop):
- Executes the statements within the body of the loop
- Tests a condition
- If the condition is true, the statements within the body of the loop are again executed
- If the condition is false, execution continues with the statements after the body of the loop

Observe, Ponder, and Journal: Section 1
- Compare this behavior to that of the while loop. What are the similarities? What are the differences?
- What are the minimum number of times that this loop will execute?
- What is the purpose of the Jump instruction after the consequent?
