==Some Code Management Issues==
==Типичные проблемы в больших проектах==
There are a few things to keep in mind when working with large DM projects. First and foremost one must strive for simplicity. The art of programming is mostly a matter of realizing your own limitations and compensating for them.
Первая и наиболее важная - поддержка простого кода. Старайтесь не использовать весь ваш код в одном файле. Думайте о возможных будущих правках и старайтесь диверсифицировать строки кода для дальнейшего удобного чтения и поиска возможных ошибок, и задания переменных. Старайтесь придерживаться модульной системы - под каждую задумку отдельный файл кода, это позволит без проблем сохранить и переносить ваши фичи с одной сборки на другую.

If, as the project grows, each new piece of code depends upon the details of every previous piece of code, the complexity of the project is growing exponentially. Before you know it, the code will rise up in revolt and stick you in a dark smelly dungeon. End of story.
По мере роста проекта, весь последующий код накладывается на предыдущий. Кроме того, код постоянно усложняется - от простых переменных - к сложным, от сложных переменных - к процедурным, от процедурных - к объектам, и так далее по нарастающей. Помните об этом и старайтесь не перекрывать и не повторять ранее использованные строки и описания.

Fortunately, most programming tasks do not require exponential complexity. With a good design, you can split the project into pieces which interact with each other in a fairly simple way. These pieces are often called modules which is why this practice is termed modular programming. (It is interesting to note, however, that all such schemes to avoid exponentially complex code ultimately fail. They only move the exponential growth to a higher level--from individual statements to procedures to objects and on and on. It may be true that complexity will always win out in the end and that every project undergoing perpetual growth must periodically be redesigned from scratch in order to remain comprehensible. Or perhaps this tendency is merely the result of a periodic increase in wisdom to offset the inevitable decline in intelligence. In my own case, I know this to be a prominent factor.)-->
Although the term module can refer to any unit of code, it most often is embodied by a file or group of files. The public parts of the module are those procedures, variables, and object types which are advertised for use by code outside the module. This is called the module interface and defines the syntax for putting information in and getting results out of the module. All other private material is considered internal to the module and is not for use by outside code.

===Ordering Code===
===Как упорядочить код===
In many cases, the sequential order of DM code makes no difference. For example, a procedure, variable, or object type may be defined before or after being used in the code. This is different from some languages which require every symbol to be defined prior to being used.
Во многих случаях, последовательность или порядок кода в Dream Maker не имеет особого значения(sic!). Например процедура, переменная или тип объекта могут быть заданы до или после их прямой компиляции. Это непривычная особенность, отличающая код DM от других, где порядок написания имеет важное значение при исполнении программ.

Последовательность кода важна в нескольких случаях. В препроцессоре,
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.
