split CUTS your string into fields. Between the beginning of string and "WINGFRAME ", there is the empty string. Example `$ perl -e " print qq!($_)\n! for split /,/, q!,1,2,3!" () (1) (2) (3) $ perl -e " print qq!($_)\n! for split /,/, q!,,,,1,2,3!" () () () () (1) (2) (3) $ perl -e " print qq!($_)\n! for split /(,)/, q!,,,,1,2,3!" () (,) () (,) () (,) () (,) (1) (,) (2) (,) (3)` [download] There is an empty string around every corner `$ perl -e " print qq!($_)\n! for split /,/, q!5,,,!" (5) $ perl -e " print qq!($_)\n! for split /(,)/, q!5,,,!" (5) (,) () (,) () (,)` [download]	[reply] [d/l] [select]
