Returns the number of characters in a string or the number of bytes required to store a variable.
Len(string | varname)
The Len function syntax has these parts:
Part Description string Any valid string expression. If string contains Null, Null is returned. varname Any valid variable name. If varname contains Null, Null is returned.
Note The LenB function is used with byte data contained in a string. Instead of returning the number of characters in a string, LenB returns the number of bytes used to represent that string.
