MAKEWORD Macro

Public Function MAKEWORD(ByVal bLow As Byte, ByVal bHigh As Byte) As Integer
	MAKEWORD = Val("&H" & Right("00" & Hex(bHigh), 2) & Right("00" & Hex(bLow), 2))
End Function

Description & Usage

MAKEWORD creates a word by concatenating two individual bytes.

Return Value

The macro returns the 16-bit integer generated by the two bytes.

Visual Basic-Specific Issues

Although it may seem unusual to use string operations for what would otherwise be a mathematical computation, it is necessary to implement MAKEWORD this way in VB. Other methods to perform this task can fail for large inputs because VB interprets them as negative values, which causes an equivalent mathematical computation to return an unwanted value.

Parameters

bLow

The low-order byte of the new 16-bit integer.

bHigh

The high-order byte of the new 16-bit integer.
