It depends on the DBM.  NDBM_File does not have exists() implemented.
DB_File does.

Read perlport, it should explain it (it comes with 5.004_05 and higher, and
is on my site and CPAN).  Basically, when reading a text file on Windows, a
CRLF will be converted into an LF, and chomp() will remove the trailing LF.
If you use binmode() on the filehandle, however, the CRLF will not be
converted, and the LF will still be removed, leaving the CR.

What is the () doing there?  That means you cannot pass any data into the
subroutine, it is an empty prototype.  Right off you are headed for
trouble.  In this case, the empty prototype is not seen until after the
subroutine is first called, so you should be "OK", but it is still Bad.
Don't use prototypes at all unless you really understand what you are
doing.  I've almost stopped using them altogether.

I am not sure what is going on.  You shouldn't have a problem like that.
Are you positive there is a newline there, and the text isn't just wrapping
to the next line?  Just throwing out a wild guess.  :)
