It had a very specific record structure for unformatted files. Normally that was almost completely hidden, except in the job control, but when we started exchanging data files with the personal computers that were then coming out, I could write programs that did the necessary conversions. Jolly good fun. My department did not use VAXes, other departments did. So, in your case these files contain data identifiable via some index. Hm, today you would do that via some library instead of via some builtin language feature, at least when using Fortran, C, C++, ...
