| 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 result has a value equal to the number of characters in STRING (if it is scalar) or in an element of STRING (if it is array valued). The setting of compiler options that specify integer size can affect the result of this function. | ||
| Specific Name | Argument Type | Result Type |
|---|---|---|
| LEN | CHARACTER | INTEGER(4) |
| CHARACTER | INTEGER(8) |
Examples
Consider the following example:
CHARACTER (15) C (50)
CHARACTER (25) D
LEN (C) has the value 15, and LEN (D) has the value 25.
