[svn-r9203] Purpose:
bug fix Description: Description: the dataset region reference data was not portable between the Cray T3E and other machines Solution: this was due to the fact that the buffer to store the heap ID and index was using a sizeof(int) for its size 4 is used instead of sizeof(int) to permit portability between the Crays and other machines (the heap ID is always encoded as an int32 anyway) Solution: Platforms tested: linux aix solaris Misc. update:
