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. * Explanation by Galleon: http://www.qb64.net/forum/index.php?topic=12193.msg105406#msg105406 ''See also: * [[ENVIRON$]] * [http://www.qb64.net/forum/index.php?topic=12204.0 64 BIT Windows Compiler Installation] {{PageNavigation}}
