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

  Choose the Recover menu item from the Maintenance pull-down menu to
  recover the selected library.  To select a library, click MB1 on the
  name of a library in the Library List box.

  Recovering a library deletes from the library any module that started
  to load but had not completed loading.  SCA cannot recover modules
  waiting to be processed; you will need to load them again.
