<!--One time when you might need to use #include directly is to force a file to be processed before the code which follows. Section 19.3.1 describes the few situations in which the order of DM source code does matter.-->

==The Preprocessor==
==Препроцессор==
The #include command is one of several preprocessor commands. They all begin with "#" and are placed on a line by themselves. (The DM preprocessor is identical to the one used in C and C++ compilers. The commands are often called preprocessor directives by C programmers.) The preprocessor handles such commands while the code file is initially being read and can be used to alter the appearance of the file as seen by the compiler. Additional preprocessor commands will be described in the following sections.
Команда #include - одна из нескольких "препроцессорных" команд. Опознать их можно по символу "#" и последовательному расположению в коде (Препроцессор Dream Maker в данном случае подобен компиляторам C и C++. Также эти люди называют команды "препроцессорными директивами). Препроцессор управляет данными командами, пока файл кода начинает исполняться и может изменять поведение файлов, в зависимости от распознавания их компилятором. Другие препроцессорные команды изложены ниже:

===#define===
Команда #define создаёт макрос(префикс) в препроцессоре. Любые участки с данным префиксом в коде будут замещены содержанием данного макроса. В местах, где макрос является частью другого слова или используется в текстовом описании, команда не сработает.
<!--command creates a preprocessor macro. Any subsequent(последующий) occurrences(случай) of the macro in the code will be replaced by the contents of the macro. Places where the macro occurs as part of another word or inside a text string do not count and will not be substituted.-->
