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 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++, ...

Regards,

Arjen
