The 3270 was the "smart" terminal. https://imgs.search.brave.com/9CW5yhzliePl3PmZJJad0-GoiArzOyOIKkKfa0cntW8/rs:fit:640:540:1/g:ce/aHR0cHM6Ly9pLnBp/bmltZy5jb20vb3Jp/Z2luYWxzLzRlL2Nk/L2JlLzRlY2RiZTBl/YjQ0YmFlNGUzOTQ4/YjVlNDk2MWY1OWMx/LmpwZw Yes, I use database libraries all the time with C/C++. Given Gnu COBOL had utilized the Berkley DB so they could provide full (or at least nearly complete) language syntax I had hoped Gnu Fortran did the same. C/C++ never provided any indexed file or "record" level support. FORTRAN always did, so I had hopes.
