Description: | Returns the length of a character expression.
Class: | Inquiry function; Generic
Arguments: | STRING | Must be of type character; it can be scalar or array valued.
| KIND (opt) | Must be a scalar integer initialization expression.
Results: | The result is a scalar of type integer. If KIND is present, the kind parameter of the result is that specified by KIND; otherwise, the kind parameter of the result is that of default integer. If the processor cannot represent the result value in the kind of the result, the result is undefined.

The setting of compiler options that specify integer size can affect the result of this function.
