ENDm ;
[Explanation]
H I LE [ conditional expression ]
(1) While the [conditional expression] holds, blocks between the next block and
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.
WHILE [ ] D01 ;
END1 ;
WHILE [ ] D05 ;
END5 ;
WHILE [ ] D01 ;
END1 ;
(2) The multiprogramming depth is up to three levels.
WHILE [ ] D01 ;
WHILE [ ] D02 ;
WHILE [ ] D03 ;
END3 ;
END2 ;
END1 ;
The flow of execution program is controlled based on the condition.
