<!--There are a few cases, however, when the order of code does matter. The preprocessor, for example, operates strictly sequentially from top to bottom of the code. The principle consequence of this is that macro definitions must precede their use. This is one good reason to instead use constant variables for the purpose when it is possible.-->

* Последовательность кода важна при наследовании процедур или переменных объекта. Если какая-либо процедура повторяется несколько раз, то она наследует последовательность выполнения первого раза.

Another time when code sequence matters is when overriding object procedures or variable initializations. If the same procedure is overridden several times in the same object type, subsequent versions take precedence and will treat previous ones as their parent procedure.

One might, for example, add functionality to the client.Topic() procedure in several different locations in the code. As long as you remember to execute the parent procedure each time, the additions are cumulative.
