Talking about pointers and memory management, I have discussed this on here before. As a CERN particle physicist I got deeply into the BOS memory management system in Fortran. https://books.google.co.uk/books/about/The_BOS_System.html?id=yUfBPgAACAAJ&redir_esc=y
This involved doing terrible, terrible things with COMMON blocks and meetings at midnight at beam crossing areas. I still am haunted by the memories.. <twitch> <twitch> On Sun, 2 Dec 2018 at 09:38, John Hearns <hear...@googlemail.com> wrote: > Interesting things coded in Fortran?
