Numeric expression indicating how many characters to return. If 0, a zero-length string("") is returned. If greater than or equal to the number of characters in string, the entire string is returned.
To determine the number of characters in string, use the Len function.
The following example uses the Left function to return the first three characters of
Dim MyString, LeftString MyString = "VBSCript" LeftString = Left(MyString, 3) ' LeftString contains "VBS".
The LeftB function is used with byte data contained in a string. Instead of specifying the number of characters to return, length specifies the number of bytes.
