# do Iteration command
Usage
    do <command> while (<condition>)
Description
Executes <command> once then evaluates the <condition>. If <condition> evaluates to true (non zero result) then repeats the execution again. <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.
Syntax Specification
    do <command> while (<condition>)
Examples
    %i = 0;
    do %i++; while(%i < 100);
    echo "After first execution:  %i";
    %i = 10
    do {
        echo "Executed!";
        %i++;
    } while(%i < 1)
    echo "After second execution:  %i";
