/sys$common/syshlp/helplib.hlb FORTRAN, Error Messages, Compilation Errors, WRONGCLD  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  SEVERITY:  F

  MESSAGE TEXT:  Wrong command definition installed - please see your
  system manager

  EXPLANATION:  The current command tables do not include the proper
  definition of the FORTRAN command.  This may be due to having
  installed an older version of the command definition, or the system
  command tables were updated but a user process is still using an
  older version.
