Right, 3270 was the terminal. Wonderful beasts :). Anyway, this reminded me of an experiment I did a couple of years ago with wrapping the BerkeleyDB library in Fortran. I never had much use for it, but it works for small enough value of "work". But this is diverting a lot from the purpose of thi

That would have been a 360/370 IBM Mini. 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 data

Well, that is indeed something completely different.My main frame of reference (pun not intentional) of that era was our IBM mini, I am not quite sure of the type number, 3270? It had a very specific record structure for unformatted files. Normally that was almost completely hidden, except in the j

Hello Arjen, Thanks for your reply. You are confusing RMS Files-11 file versioning with Indexing. Sorry, this got away from me. Once I started I couldn't stop. Real computers, didn't matter who made them or their OS, all provided at least one type of indexed file. These were business class pl

I have never worked much with VAXes, but I do remember that VAX used a file system where you made a new version of a file and the older versions were automatically kept. I guess that is the purpose of the INDEXED organisation. It is not so much a limitation of gfortran that it does not support this
