VSI Fortran provides the following intrinsic data types:

   o  INTEGER (4 kind type parameters) - a whole number

   o  REAL (3 kind type parameters) - a floating point number (a
      whole number, a decimal fraction, or a combination)

   o  DOUBLE PRECISION - a REAL kind type parameter that has more
      than twice the degree of accuracy in its representation, and
      greater range

   o  COMPLEX (3 kind type parameters) - a pair of REAL values
      representing a complex number (the first part of the number is
      the real part, the second is the imaginary part)

   o  DOUBLE COMPLEX - a COMPLEX kind type parameter with DOUBLE
      PRECISION real and imaginary parts

   o  LOGICAL (4 kind type parameters)- a logical value, .TRUE.  or
      .FALSE.

   o  CHARACTER - a sequence of characters

   o  BYTE - a one-byte value equivalent to INTEGER(KIND=1)
