If you're dealing with csv, then I strongly recommend using Text::CSV_XS. Said this... 
#!/usr/bin/perl

$infile = @ARGV[0];
$outfile = "OK.txt"; 
$outfile2 = "ERROR.txt";      
@Filter = ('01005;01000','01005;01001','01005;01002','01005;01003');
$zaehler = 0;

Hmmm no strict, no warnings. Now, that is too bad... 
open(INFILE, "< $infile")
or
die "\nDatei $infile konnte nicht geoeffnet werden\n";

[download]
Better: 
open my $in, '<', $infile or
  die "Error message including \$!: $!\n";

[download]
and ditto as above wrt the other opens. 
while (<INFILE>) { print OUTFILE if /@Filter[0]/; }

Huh?!?
