MQBYTE on IBM i

The MQBYTE data type represents a single byte of data.

No particular interpretation is placed on the byte-it is treated as a string of bits, and not as a binary number or character. No special alignment is required.

An array of MQBYTE is sometimes used to represent an area of main storage with a nature that is not known to the queue manager. For example, the area might contain application message data or a structure. The boundary alignment of this area must be compatible with the nature of the data contained within it.
