When ASCII was designed teletype like applications were still prevalent. Lots of printing instead of outputting to displays. Nowadays, it's of course a bit wasteful that of the first 32 characters of the most used character set only about one third is still being used. And it's pretty sad that the separators control characters are not used. We could have a much better CSV with them instead of the error prone CSV we have know. But FWIW I almost daily use BEL.
