in reply to Record Separator affecting Regex

... This should be darn simple, but I can't make it work. It's quite a simple concept: make the record separator ";\n" and filter-out all lines that start with a # -- comments.

First off: Are you sure the current record selector is '\n'. If this is running on a windows machine it is '\r\n' (or do I mean '\n\r'? who cares). In any case the safe way to get the new descriptor is to do (with local if required) 

$/= ';'.$/

But actually I think you shoud be not monkeying with $/: at all and just skipping over # lines as you read them in, i.e. 
while (my $line = <DATA> ){
   next if ($line =~ s/^#/); # skip comment lines
   print "Query: $line\n";
}
