Right. This is what I was hinting at: The thing is that a matter of practise, one ends up with a flood of UNIX, MacOS, and MSOS files via the Internet, and it is difficult to keep track which files that should be translated, and which one should not. Therefore, at least for computer related software, such as for compilers and their text editors, it is now common on the MacOS that they use that Java convention or something similar. Thus, I do not anymore translate the text files I pick down, but merely give them the attribute 'TEXT', even though they have UNIX newlines in them. Experimenting though with Hugs (that is, the sources I ported to MacOS), I found it tricky to write UNIX newlines, because sometimes one writes to a console, and it does not accept \n as newlines. So the safe thing is to write files as "text", whereas reading them with the Java convention, either by tweaking the library routines, or by opening the files as binary and do the parsing then. -- But with the latter approach, one will have to check what happens under VMS and other platforms that have yet other conventions. Another approach would be to make a TeX version that pretends to be 32-bit internally, and require the \r, \n, and \r\n newlines to be translated into the Unicode line separator. Hans Aberg
