'''#if''' <what to check>
:<if block>
['''#else
:<else block>]
'''#endif'''

Checks if ''what to check'' is true. If it is, the code in ''if block'' will be compiled. If it isn't, the code in ''else block'' will be compiled or when there is no ''else block'', the compiler will continue after [[precompiler_endif|#endif]].

== Example ==
Consider a define to set the framepercentage in a certain process. Now for some reason you might want to just have a frame; compiled when that define is set to ''100''.
<pre>
Loop
#ifdef FRAMEPERC
#if FRAMEPERC == 100
frame;
#else
frame(FRAMEPERC);
#endif
#else
frame;
#endif
End
</pre>
Used in example: [[Loop]], [[End]], [[frame]], [[precompiler_if|#if]], [[precompiler_else|#else]], [[precompiler_endif|#endif]]
