By Steve Lionel (Ret.) Posted on 06/23/18 0
At the June 2018 meeting of the International Fortran Standards Committee (WG5) in Berkeley, California, we processed 84 comments received during the ISO ballot of the Draft International Standard (DIS).

Two significant events happened recently in the Fortran world. As I wrote in Doctor Fortran in "DIS, Dat and Doze", the Draft International Standard for Fortran 2018 was submitted for country ballot back in January.
