I have written a package called Direct_Text_IO. It is a mixture of Direct_IO
and Text_IO, i.e. it allows random access in a text file.
It provides usual operations on Character and strings, and deals properly
with end of lines and end of pages.
It is not finalized (i.e. I didn't yet write the documentation); once it is
done, I will put it on Adalog's components page.
In the mean time, send me a note if you want to try it (my ISP refuses
attachments in this newsgroup).
Feel free to use it and report any problem you may encounter !
