Hi!


I'm running GNAT 3.09 (gcc 2.72) on a Sun Solaris 2.5.
I have trouble detecting special characters in a textfile
that I read.

In the source text file that I read, pages are separated
with FF (FormFeed) characters, you know ASCII 12. =


In the files the FF-character can appear at any place on =

a line. The Ada.text_io-package can only detect new-page
as a combination of <new-line><ff> which is not satisfactory
for me. None of the ways I've tried, reading single characters
from the file, will return a FF-character. =


The opposite is on the other hand possible. I can write to
text files using ada.text_io.put(character'val(12)) and
it will appear on the outfile anywhere on a line, but then =

I can't read it back and detect the FF. =


If anyone can help me with this problem I'll be very happy!

Please help me! =


  /Jakob :)

PS: Please also make a direct reply to my e-mail! =
