EXIT                     Exit Multiline Function, Loop, or Subprogram

 EXIT {DEF | DO | FOR | SUB}

    Exits a multiline function definition, a DO loop, a FOR loop, or a
    subprogram.

   ----------------------------------------------------------------------

      Notes:    The construct definition is not ENDed by the EXIT
                statement. An END statement is still required.

                Premature exit from a nested DO or FOR loop transfers
                control to the immediately enclosing loop.
