Using and Porting GNU Fortran

[ < ] [ > ]   [ << ] [ Up ] [ >> ]         [Top] [Contents] [Index] [ ? ] Len Intrinsic


Len: INTEGER(KIND=1) function.

String: CHARACTER; scalar.

Intrinsic groups: (standard FORTRAN 77).


Returns the length of String.

If String is an array, the length of an element of String is returned.

Note that String need not be defined when this intrinsic is invoked, since only the length, not the content, of String is needed.

See section Bit_Size Intrinsic, for the function that determines the size of its argument in bits.
