This function can be used to add a while loop to script code.
%Loop.While( x condition y ) { ... }
You can use the following conditions:
= (x equal y)
< (x less than y)
> (x greater than y)
! (x not equal y)
<= (x less or equal than y)
>= (x greater or equal than y)
While the condition "x condition y" is true, the script code enclosed by { } is processed.

Example:
%Loop.While(1=1) Then { "infinite loop" }
The condition is 1=1. Its always true, so the script code enclosed by { } is processed over and over again.
