Programming

Chapter 8

Description:

1. This command repeats the commands contained in the loop as long as its condi-

tion is true (non-zero). When the condition becomes false (0), execution pro-
ceeds from the statement following the WhileEnd-statement.

2. Since the condition comes after the While-statement, the condition is tested

(checked) before the commands inside the loop are executed.

Example: 10

→ A_

While A > 0

_

A – 1

→ A_

”GOOD”
