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

  /[NO]WARNINGS[=(option[,...])]  D=/WARNINGS=(GEN,UNCAL,UNINI,UNREA,UNUS,USAGE)

  Controls whether the compiler generates certain classes of optional
  diagnostic messages.

  Specifying /WARNINGS without arguments has the same effect as
  specifying /WARNINGS=ALL; specifying /NOWARNINGS has the same
  effect as specifying /WARNINGS=NONE.

  The default is:  /WARNINGS=(NOALIGNMENT, NOAlpha,
  NODECLARATIONS, GENERAL, NOINLINE, NOTRUNCATED_SOURCE, NOULTRIX,
  UNCALLED, UNINITIALIZED, UNREACHABLE, UNUSED, USAGE, NOVAXELN).
