The piece of code below is supposed to read 20 lines of an existing text file and set a mark ($marke) so the next time this piece of code gets executed, it would then skip the first $marke lines.

When $marke is still zero, everything goes as planned. Oddly, in the second run when $marke is 21, the file is not read line-by-line like it was in the first run, but the whole file goes into the $zeile string. Why?

The documentation and tutorials don't cover this problem. Is there something like line context (not exactly) that I could force my filehandle into?

open(TODO,"<datei.txt") or &fehler;
while ($zeile=<TODO>) {
 print "$counter $zeile\n"; # debugging: what is actually read?
 chomp $zeile;
 next if ($counter<$marke);
 if ($counter>($marke+20)) { $stilltodo=1; last; }
 push (@liste,$zeile);
 $counter++;
}
close(TODO);

Update: corrected "line contest" to "line context". Problem is solved now, see below.
