NEQV (3sciport)

Computes logical difference

SYNOPSIS

  boolean = NEQV( arg1, arg2 )

FUNCTION VALUE

  neqv            Boolean. (Integer, Logical, or Real.)
                  The bit-wise boolean .XOR. of two 64 bit data items.

ARGUMENTS

  arg1            Integer, Logical, or Real.
                  A 64 bit input argument.

  arg2            Integer, Logical, or Real.
                  A 64 bit input argument.

DESCRIPTION

  The external function NEQV returns the bit-wise boolean .XOR. of the input
  arguments, arg1 and arg2.

NOTES

  Since NEQV is not an ANSI Fortran 77 intrinsic function, it must be
  declared as an external function of type integer, logical or real. For
  example:

          EXTERNAL NEQV
          INTEGER  NEQV
          ...
          I = NEQV( X,'F0F0F0F0F0F0F0F0'X,'C3C3C3C3C3C3C3C3'X )
                                          ! Same as I = '3333333333333333'X
