  SEVERITY:  F

  MESSAGE TEXT:  INCLUDE not supported for current source file device

  EXPLANATION:  An INCLUDE statement was found while the current
  source device was not random-access, for example a tape drive or a
  terminal.  The compiler requires that it be able to close and later
  reopen and reposition the source file before processing an INCLUDE
  statement.
