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

Len(string | varname)

Arguments

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.
