The _OS$ function returns the operating system and QB64 compiler bit version used to compile a QB64 program.
Syntax
- compilerVersion$ = _OS$
Description
- Returns a STRING listing the OS as [WINDOWS], [LINUX] or [MACOSX] and the compiler bit format of [32BIT] or [64BIT]. Example: [WINDOWS][32BIT]
- Allows a BAS program to be compiled with QB64 in Windows, Linux or macOS using different OS or language specifications.
- Use the return 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 macOS use 64 bit by default.
- Important Note
- Even if you're on a 64-bit Windows system, the _OS$ function may return [32BIT].
- That is, if your program was compiled with the 32-bit version of QB64, hence it's a 32-bit executable running on 64-bit Windows.
- This is by design and not a bug, as your program gets the information it needs to run (e.g. to use 32-bit or 64-bit DLL using DECLARE DYNAMIC LIBRARY) and not what you as user would expect to see according to your system.
- That's why the "used to compile" phrase was printed bold in the first line above.
