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

All, I'm getting back into Fortran after many years away and was going to start with my goto kick the tires application. Basically the lottery tracking system found in this book. https://www.theminimumyouneedtoknow.com/app_book.html The first cut was Fortran 77 on the VAX. There we could cre
