ntoint32(N)
int32ton(INT32)
     :: Type-conversion between a non-negative integer and an unsigned
     32bit integer.

RETURN
     unsigned 32bit integer or non-negative integer

N
     non-negative interger less than 2^32

INT32
     unsigned 32bit integer

   * These functions do conversions between non-negative integers (the
     type id 1) and unsigned 32bit integers (the type id 10).

   * An unsigned 32bit integer is a fundamental construct of OpenXM and
     one often has to send an integer to a server as an unsigned 32bit
     integer. These functions are used in such a case.
