Len

This function determines the number of characters in a string or the number of bytes required to store a variable.

Syntax

Len(string | varname)

Parameters

string

Any valid string expression. If string contains Null, Null is returned.

varname

Any valid variable name. If varname contains Null, Null is returned.

Return Values

Remarks

In addition to Len, you can use the LenB function 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.
