When iteration is indicated for an element or a group of elements in the data dictionary DO WHILE, DO UNTIL, or PERFORM UNTIL structured English statements must be included
There are three primary types of control structures in structured English: DO WHILE, DO UNTIL, and PERFORM UNTIL. Each has a specific purpose and use cases.
DO WHILE is used when you want to iterate an element or group of elements until a certain condition is met. For example, you may want to DO WHILE a certain number is less than 10.
DO UNTIL is used when you want to iterate an element or group of elements until a certain condition is no longer true. For example, you may want to DO UNTIL a certain number is greater than 10.
PERFORM UNTIL is used when you want to repeat an action until a certain condition is met. For example, you may want to PERFORM UNTIL a certain number is equal to 10.
Each of these control structures has its own advantages and disadvantages. It's important to choose the right one for the task at hand. In general, DO WHILE and DO UNTIL are best for looping through data, while PERFORM UNTIL is best for repeating an action.
