Len Function

Office VBScript

Microsoft® Visual Basic® Scripting Edition Len Function  Language Reference 
Version 1 


Description
Returns the number of characters in a string or the number of bytes required to store a variable.
Syntax
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.

Remarks
The following example uses the Len function to return the number of characters in a string:
Dim MyString
MyString = Len("VBSCRIPT") ' MyString contains 8.

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.
