The LOOP statement denotes the end of a DO…LOOP where the program jumps to the beginning of the loop if the optional condition is true.

Syntax

DO . . . LOOP [{UNTIL|WHILE} condition]

• LOOP indicates the bottom or end of a DO…LOOP block of code.
• Either the DO…LOOP statement or LOOP statement can set a condition to end the loop.
• When a loop uses a LOOP condition, the code inside of it will run at least ONCE.

  • A WHILE condition continues the loop until the condition is false.
  • An UNTIL condition continues the loop until the condition is true.
  • If only DO and LOOP are used the loop will never end! Ctrl-Break can be used to stop an endless loop!

• DO LOOPs can also be exited using EXIT DO or GOTO.
