Library /sys$common/syshlp/macro$dwci.hlb commands, quit  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Choose the Quit menu item to cancel the compilation and
  return to the window from which you invoked the dialog
  box, for example, a FileView or LSE window.  (Choosing
  this menu item has the same effect as choosing the
  Cancel button in the main dialog box.)
