 The term <i>sub</i> is short for subroutine. Subs are an important feature of the EasyUO script that will make your scripts more logically structured, easier to read, and will make you have to write less code.

 The loop starts by assigning the ''from_value'' to the variable, runs the statement(s) inside the code block.
