WHILE ~ WEND #

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

Name	Description
`WHILE`	The `WHILE` keyword is the start of a `WHILE` block.
`condition`	An expression that results in a true or false value.
`<body>`	Code within the `WHILE` block is executed at each iteration of the loop.
`WEND`	The `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.)
