is the US Fortran standards committee, known formally as PL22.3,
a technical subcommittee of the InterNational Committee
for Information Technology Standards
formerly known as the National Committee for Information Technology
J3 developed the Fortran 66, Fortran 77, Fortran 90, Fortran 95,
Fortran 2003, and Fortran 2008 standards. Fortran 2008 is
an upwardly-compatible extension of Fortran 2003, adding, among other
things, more expression of parallel computation (via coarrays and
the do-concurrent construct), improved facilities for data organization
(via enhancements to modules), and an enlarged intrinsic library
(with more mathematical and bit-manipulating procedures).
Working closely with ISO/IEC/JTC1/SC22/WG5
(see "WG5"), the
international Fortran standards committee, J3 is the primary development body
for a TS to improve the Interoperability with C features,
and a TS to extend further the coarray features. J3 continues
to process interpretation requests, and is working with WG5
to add a Fortran contribution to TS 24772, published by WG23.

J3 meetings, documents, and membership are open to anyone worldwide.
