SHIFTR - Performs a right shift with zero fill

As shipped in IRIX 6.5.7. Last changed in IRIX 6.5.5.

NAME
     SHIFTR - Performs a right shift with zero fill

SYNOPSIS
     SHIFTR ([I=]i,[J=]j)

IMPLEMENTATION
     UNICOS, UNICOS/mk, IRIX systems

     CF90, MIPSpro 7 Fortran 90

STANDARDS
     Fortran extension

DESCRIPTION
     The SHIFTR intrinsic function performs a right shift with zero fill of
     the i by j bits.  It accepts the following arguments:

     i         The value to be shifted.  i can be of type Boolean, integer,
               real, or Cray pointer.

     j         The number of bits to shift the value.  Must be of type
               integer or Boolean.  j must be within the range
               0 <= j <=size, where size is the size, in bits, of i.  That
               is, if i is a 64-bit object, j must be within the range
               0 <= j <= 64.

     On UNICOS systems, an object is 64 bits.  On UNICOS/mk systems, an
     object is 32 bits or 64 bits.  On IRIX systems, an object is 8 bits,
     16 bits, 32 bits, or 64 bits.

     SHIFTR is an elemental function.  The name of this intrinsic cannot be
     passed as an argument.

NOTES
     This is an outmoded routine.  Refer to the Fortran Language Reference
     Manual, Volume 2, for information about outmoded features and their
     preferred standard alternatives.

     The bit representation of the logical data type is not consistent
     among UNICOS and UNICOS/mk systems.  For further details, see your
     compiler's reference manuals.

RETURN VALUES
     SHIFTR returns a value of type Boolean on UNICOS and UNICOS/mk
     systems.  It returns an integer result on IRIX systems.

EXAMPLES
     The following section of Fortran code shows the SHIFTR function used
     in the case where i is of type integer.  The bit pattern of i and the
     bit pattern of the result are also given.  For simplicity, a 16-bit
     object is used.

          INTEGER I1, I2, I3
          ...
          I2 = 5
          I3 = SHIFTR(I1,I2)
