Syntax of the Byte Data type in Excel VBA

Let us see Data Type Byte Syntax in Excel VBA.

Dim VariableName As Byte

Where VariableName represents the name of the variable.
The Byte represents the data type of the variable.

Example1: The Byte variable value is 200

Here is an example on Byte VBA Data Type in Excel VBA when value is 200.

Sub VBAF1_Byte_DataType()
    
    'Variable declaration
    Dim bByte As Byte
    
    'Assign value to variable
    bByte = 200
    
End Sub

Example2: The Byte variable value is 400

Let us see one more example when value is 400.

Sub VBAF1_Byte_DataType()
    
    'Variable declaration
    Dim bByte As Byte
    
    'Assign value to variable
    bByte = 400
    
End Sub

Example3: The Byte variable value is negative

Sub VBAF1_Byte_DataType()
    
    'Variable declaration
    Dim bByte As Byte
    
    'Assign value to variable
    bByte = -600
    
End Sub

The above two macro throws an error. Because the byte variable value is more than 255 in the second example and value is negative in third example. Here is screenshot for your reference.
