VMS Help FORTRAN, Statements, INQUIRE, ERR  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  ERR = s

  s  Is the label of an executable statement.

  ERR is a control specifier rather than a property specifier.  If an
  error occurs during the execution of the INQUIRE statement, control
  is transferred to the statement whose label is "s".
