ENDm block are executed repeatedly, and when it does not hold, execution shifts
to the block next to ENDm.
(2) WHILE [conditional expression] DOm and ENDm are used in pairs.
The range of identification No. m is 1 to 32.
(3) The multiprogramming depth of the WHILE statement is up to three levels.
[Example] (1) The identification No. m can be used any number of times as
desired.
