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


{{PageSyntax}}
:::: compilerversion$ = '''_OS$'''


* Allows a BAS program to be compiled with QB64 in Windows, Linux or MacOSX using different OS or language specifications.
* Use the return to specify the current OS code to use when a BAS program is compiled using another version of the QB64 compiler.
* Returns a [[STRING]] listing the OS as [WINDOWS], [LINUX] or [MACOSX] and the compiler bit format of [32BIT] or [64BIT]. 
* Windows can use either a 32(default) or 64 bit compiler. Linux and Mac use 64 bit. '''Example: {{text|[WINDOWS][32BIT]|green}}'''
* Note: It may not be possible to run a QB64 EXE program compiled on another operating system to get an _OS$ return value.
