New page

[[category:precompiler]]

== Definition ==
'''#define''' <what to define> [<what it will be>]

Defines ''what to define'' as ''what it will be''. This means that after this line, all ''what to define''s will be "replaced" by ''what it will be''.

== Example ==
In the following example, we'll show it is possible to define words as "being" [[basic statements]].
<pre>
#define StartThisShow Program
#define GimmeSomeShit Process

StartThisShow example;
Begin
proc();
End

GimmeSomeShit proc()
Begin
End
</pre>
Used in example: [[Program]], [[Process]], [[Begin]], [[End]]

Error codes are handy as well, like used in [[Network.DLL]] and [[LCD.DLL]]:
<pre>
#define NET_ERROR_INVALIDADDRESS -12
</pre>
This will enable the use of NET_ERROR_INVALIDADDRESS as it it were the value -12. This makes it much more clear for the programmer what the errors are. Consider this:
<pre>
#define NET_STATUS_ESTABLISHED 2
</pre>
The value ''2'' on itself means very little, but ''NET_STATUS_ESTABLISHED'' immediately makes it clear what it means.
