Preprocessor directives allow to determine preprocessor behaviour, e.g ignoring blocks of code depending on certain conditions.

For use cases, see e.g {{Link|Arma Reforger:Scripting Temporary Feature|Scripting Temporary Feature}}.

| <enforce>#define MY_FLAG</enforce>
|-
|
=== #ifdef ===
| Open a preprocessor scope that is considered if the provided flag is defined. The scope must be ended by {{hl|#endif}} (see below).
| <enforce>
#define MY_FLAG

#ifdef MY_FLAG
Print("Flag is defined");
#endif
</enforce>
|-
|
=== #ifndef ===
| Open a preprocessor scope that is considered if the provided flag is '''not''' defined. The scope must be ended by #endif (see below).
| <enforce>
#define MY_FLAG

#ifndef MY_FLAG
Print("Flag is not defined");
#endif

</enforce>
|-
|
=== #else ===
| Add a preprocessor scope that is of the opposite condition of the current {{hl|#ifdef}}/{{hl|#ifndef}}. The scope must be ended by #endif (see below).

#ifdef MY_FLAG
Print("Flag is defined");
#else
Print("Flag is not defined");
