The [[_OS$]] function returns the operating system and QB64 compiler bit version used to compile a QB64 program.


{{PageSyntax}}
: {{Parameter|compilerVersion$}} = [[_OS$]]


{{PageDescription}}
* Returns a [[STRING]] listing the OS as [WINDOWS], [LINUX] or [MACOSX] and the compiler bit format of [32BIT] or [64BIT]. Example: {{text|[WINDOWS][32BIT]}}
* Allows a BAS program to be compiled with QB64 in Windows, Linux or MacOSX using different OS or language specifications.
* Use the return {{Parameter|compilerVersion$}} to specify the current OS code to use when a BAS program is compiled using another version of the QB64 compiler.
* Windows can use either a 32 (default) or 64 bit compiler. Linux and Mac use 64 bit by default.
