Parameters
- wValue
- Type: Word
The number whose low-order byte you want to get.
Return Value
Type: ByteRemarks
Related data can be stored in the high-order and low-order words of a variable.
Therefore, instead of creating and returning a 2-element array, it may be more efficient to return a word whose 2 bytes contain separate information.

Examples
The Windows API function GetVersion() returns the DOS version in the high-order WORD and the Windows version in the low-order WORD. Moreover, the DOS major number is in the high-order byte of its WORD, the DOS minor number is in the low-order bytes of its WORD, the Windows major number is in the low-order byte of its WORD, and the Windows minor number is in the high-order byte of its WORD:
