WHILE ~ WEND

Root / Documentation / [.]

Created:
A WHILE block creates a loop that runs while a condition is true. The condition is evaluated at each iteration, so if it changes to false, the loop will exit.

Syntax

WHILE condition
 <body>
WEND
NameDescription
WHILEThe WHILE keyword is the start of a WHILE block.
conditionAn expression that results in a true or false value.
<body>Code within the WHILE block is executed at each iteration of the loop.
WENDThe WEND keyword is the end of a WHILE block.

Examples

The WHILE loop is used to repeat a block of code while some trivial condition remains true. The condition must have some way to change within the loop, otherwise the loop will continue forever (unless a statement within contains BREAK or some other means of escape.)
