Hello, 
my $covCounter = 0;
open(EVALUATION, "< $evalFile[0]") or die $!;
undef $/;
(my $shortFile = <EVALUATION>) =~ s/^.+-+ END -+//gs;
$shortFile =~ /(?(^(\d+ )+\s+(\d+)+$)(?{$covCounter++}))/gm;
close EVALUATION;

I get always the message "unknown switch condition m/(?(<--HERE". Why unknown? Where is my fault? Thats supposed to be a if then Regex with an integrated Perl counter. What do I wrong? Thank you very much for your help.
