Library /sys$common/syshlp/lse$menu.hlb SET_SAVE_RELATED_BUFFERS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Syntax:  SET SAVE RELATED BUFFERS boolean

  Determines if related modified buffers are written out on COMPILE
  commands.

  If this attribute is on, all modified buffers with the same language
  as the buffer being compiled are written out before the compilation
  takes place.  If this attribute is off, any modified buffers with the
  same language are not written out.
