Returns the number of characters in a specified character string.
The character string whose length you want to find.
LEN( ) returns the number of characters (the length) of a character string or memo field. The length of an empty character string or empty memo field is zero. When LEN( ) calculates the length of a memo field, it counts two characters for each carriage-return and linefeed combination (CR/LF).
Other than the syntactic difference of reading a property instead of calling a function, length contains the same value that LEN( ) returns.
