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

  /[NO]BLAS=(option[,...])            D=/BLAS=(INLINE,MAPPED)

  Controls whether Compaq Fortran 77 recognizes and inlines or maps Basic
  Linear Algebraic Subroutines (BLAS), Level 1 (Basic or Extended
  Set).

  The default is /BLAS=(INLINE,MAPPED), equivalent to /BLAS=ALL.
  This qualifier can also be specified on the OPTIONS statement.

  For more information on these routines, see your language reference
  manual or Intrinsic_Functions in this Help file.

  The BLAS Level 1 routines are as follows:

  +---------------------+---------------------+
  | Basic Set           | Extended Set        |
  +---------------------+---------------------+
  | IxAMAX     xNRM2    | IxAMIN     xNORM2   |
  | xASUM      xROT     | IxMAX      xNRSQ    |
  | xAXPY      xROTG    | IxMIN      xSET     |
  | xCOPY      xSCAL    | xAMAX      xSUM     |
  | xDOTx      xSWAP    | xAMIN      xVCAL    |
  |                     | xMAX       xZAXPY   |
  |                     | xMIN                |
  +---------------------+---------------------+

  Note that the Compaq Extended Math Library product may be needed
  to resolve references to BLAS Extended Set routines that are not
  expanded inline by the compiler.

                                 NOTE

          You should not overlap  output  arrays  with  input
          scalars  passed  to  BLAS routines.  This can cause
          incorrect results.
