Left
Use the Left function to return a specified number of characters from the
      left side of a string.
    The Left function returns a variant(string). To determine the number of
      characters in a string, use the Len function.
Syntax
Left(string, length)
| Argument | Description | 
|---|---|
string | 
              String expression from which characters are returned. If
                  string contains Null, then Null is returned. | 
            
length | 
              Variant (Long). Numeric expression indicating how many characters to return. If 0, then a zero-length string ("") is returned. If greater than or equal to the number of characters in string, then the entire string is returned. | 
Use the LeftB function with byte data contained in a string. Instead of
        specifying the number of characters to return, length specifies the number
        of bytes.
Example
This example returns "To the left":
Left("To the left of this sentence",11)
