ISO/IEC JTC1/SC22/WG5-N2261

                  WORK ITEMS FROM THE WG5 MEETING
        HELD ON JUNE 15 AND 19, 2026 AT WARWICK UNIVERSITY, UK

This is the work item list for the next revision of ISO/IEC 1539:2023
Fortran, referred to as Fortran 202Y, as adopted by WG5 at its 2026 
meeting in Warwick University, UK. It incorporates changes made from
the previous list (N2249).

This list is subject to amendment by WG5. References are to ISO WG5
N-documents or INCITS/Fortran papers (yy-nnn), but please understand that
this work item list is for general concepts and that development of the
features will be done by INCITS/Fortran, and may or may not closely resemble
detailed descriptions in the referenced papers.
