Len Function

Microsoft® Visual Basic® Scripting Edition
Len Function

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.

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.
