Len returns a long value specifying the number of characters in a string, or the number of bytes required to output a variable. The optional parameter, ''string'', is any valid string expression. The optional parameter, ''variable'', is any variable. If ''variable'' contains a string, the length of the string is returned. One (and only one) of the optional parameters, ''string'' and ''variable'', must be supplied.
