ON, ERROR
^*Conan The Librarian (sorry for the slow response - running on an old VAX)

  The ON ERROR statement transfers program control to a  specified  line
  or program module.  If an error is pending when the ON ERROR statement
  executes, control is transferred immediately.  Otherwise,  control  is
  transferred  when an error occurs.  For new program development, it is
  recommended that you use WHEN blocks.
