Dialect Differences


  • Threading is not allowed in the -lang qb dialect.

Platform Differences


  • The DOS version of FreeBASIC does not allow for threads, as the OS does not support them.
  • In Linux the threads are always started in the order they are created, this can't be assumed in Win32. It's an OS, not a FreeBASIC issue.
