Every time you cat a BSV file, your terminal beeps like it's throwing a tantrum. A record separator (RS) based file would be missing this feature! In other words, my previous comment was just a joke! :)
By the way, RS is decimal 30 (not octal '\030'). In octal, RS is '\036'. For example:
$ printf '\036' | xxd -p
1e
$ printf '\x1e' | xxd -p
1e
