The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

─────Yielding Control to Windows────────────────────────────────────────────
 
     Applications must occasionally yield control so that Windows can
     update the screen, respond to user input, and allocate processor
     time to other running applications. The YIELDQQ subroutine yields
     control to Windows.
 
     NOTE: YIELDQQ is not the same call as the Windows API Yield()
     call; QuickWin applications must use YIELDQQ.
 
     The interface is defined as follows:
 
          INTERFACE TO SUBROUTINE YIELDQQ()
          END
 
     The compiler adds some YIELDQQ calls automatically. YIELDQQ calls
     improve the responsiveness of an application to other
     applications and Windows updates, but these calls increase the
     time required for the application to complete execution.
