Someone reported this bug earlier to bugs@spirits.ka.sub.org and I don't
remember who it was, but this problem should be fixed now, so I decided to post.

Arn uses LONG integers for article numbers, but because of a missing ANSI-C,
I forgot the (RIGHT) function prototypes, so that longs were casted to short
integers. This should be fixed in Version 0.67e. It is available on abcfd20
via a-ftp in /incoming/amiga/AmigaUUCP_Plus (see my posting in this group).

I hope that this is no longer true for versions >0.67e of Arn.

I will distribute the Arn-Source as soon as the kill-file is implemented
(which is currently not! :-().

That's true!!

I hope that this is no longer necessary. Get the newest version of Arn!
Because I'll be on holiday for the next three weeks and my site spirits is
offline for this time don't complain for late replies. All E-Mail to me
will naturally be saved, but I can't read your follow-ups, so you SHOULD REPLY
by mail on this posting.

Thanks,
 Roland
