MQUINT64 - 64 bit unsigned integer

The MQUINT64 data type is a 64 bit unsigned integer that can take any value in the range 0 through +18 446 744 073 709 551 615 unless otherwise restricted by the context. For COBOL, the valid range is limited to 0 through +999 999 999 999 999 999. An MQUINT64 should be aligned on a 8 byte boundary.
