For convenience this section collects a list (probably incomplete) of the Fortran 90 features supported by the GNU Fortran language, even if they are documented elsewhere. See Characters, Lines, and Execution Sequence, for information on additional fixed source form lexical issues. Further, the free source form is supported through the -ffree-form option. Other Fortran 90 features can be turned on by the -ff90 option; see Fortran 90. For information on the Fortran 90 intrinsics available, see Table of Intrinsic Functions.
") as well as single quotes. See Character Type.
STATUS='REPLACE'is supported. The
FILE=specifier may be omitted in an
Zedit descriptor is supported.
>=may be used instead of
KIND. See Kind Notation. (
KINDis of limited usefulness in the absence of the
KIND-related intrinsics, since these intrinsics permit writing more widely portable code.) An example of supported
INTEGER (KIND=1) :: FOO=1, BAR=2 CHARACTER (LEN=3) FOO
DIMENSION attributes aren't supported.
