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

  SSCAL   (n, a, x, incx)
  DSCAL   (n, a, x, incx)
  CSCAL   (n, a, x, incx)
  CSSCAL  (n, a, x, incx)
  ZSCAL   (n, a, x, incx)
  ZDSCAL  (n, a, x, incx)

  Subroutines that scale the elements of an array by a scalar value.

  These routines are part of the BLAS1 Basic Set, and are only
  available on VAX processors.

  Arguments

    n

    Integer number of elements in array "x" to be accessed.

    a

    Scalar value to be multiplied by each selected element in array
    "x".  The data type is REAL*4 for SSCAL and CSSCAL, REAL*8 for
    DSCAL and ZDSCAL, COMPLEX*8 for CSCAL and COMPLEX*16 for ZSCAL.

    x

    Array containing the elements to be scaled or array reference to
    the first such element.  The selected elements are replaced by
    the scaled value.  The data type is REAL*4 for SSCAL, REAL*8 for
    DSCAL, COMPLEX*8 for CSCAL and CSSCAL, COMPLEX*16 for ZSCAL and
    ZDSCAL.

    incx

    Integer index increment used in selecting which elements of array
    "x" are accessed.
