Description

The STRLEN() function returns the output width of the specified expression <exp>. The expression can be of any data type, including memo fields and arrays. When checking the length of character expressions, the optional <expL> can be specified. If <expL> is specified and evaluates to .T. (true), the STRLEN() function will return the length of the character expression after stripping any formatting options such as BOLD().
