Yeah, that's history, isn't it? fopen() is used for text directly. That
seems to be part of the Unix heritage of C and I would think it does
have it's advantages. After all the vast majority of Unix tools and
Unix-style tools are dealing with text only.

That's basically what I thought. I would try to keep this text mode
layer very simple and small though. When you talk about "TAL" in my mind
I get the image of some library that does all kind of things even
including hooks for stuff like HTML, SGML, and I-don't-know-what-else.
Nice, but I would not want it in the basic RTL. OTOH if we are talking
about ASCII text, with only support for Unix, DOS and Mac line ends,
that would be what I need for ported tools right now. And it's very easy
to implement in just a few lines.


so long, benny
