Intel® Fortran Compiler 17.0 Developer Guide and Reference
Elemental Intrinsic Function (Generic): Returns the length of the character argument without counting trailing blank characters.
result = LEN_TRIM (string [, kind])
string |
(Input) Must be of type character. |
kind |
(Input; optional) Must be a scalar integer initialization expression. |
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 remaining after any trailing blanks in string are removed. If the argument contains only blank characters, the result is zero.
The setting of compiler options specifying integer size can affect this function.
LEN_TRIM (' C D ') has the value 4.
LEN_TRIM (' ') has the value 0.
The following shows another example:
INTEGER LEN1
LEN1 = LEN_TRIM (' GOOD DAY ') ! returns 9
LEN1 = LEN_TRIM (' ') ! returns 0
