# while Iteration command
Usage
    while (<condition>) <command>
Description
Executes <command> while the <condition> evaluates to true (non zero result). <command> may be either a single command or a block of commands. It can contain the break command: in that case the execution of the <command> will be immediately interrupted and the control transferred to the command following this while block. It is valid for <command> to be an empty command terminated with a ';'. <condition> is an expression as the ones evaluated by [doc:expressioneval]$(*)[/doc] with the following extensions: If <condition> is a string, its length is evaluated: in this way a non-empty string causes the <condition> to be true, an empty string causes it to be false. If <condition> is an array, its size is evaluated: in this way a non-empty array causes the <condition> to be true, an empty array causes it to be false. If <condition> is a hash, the number of its entries is evaluated: in this way a non-empty hash causes the <condition> to be true, an empty hash causes it to be false.
