Join with '': a) a randomly selected entry from @a excluding the digits at positions 0..9 [the part between the 1st and 2nd comma] b) five randomly selected entries from @a [the map part] Note: @a is used in scalar context both times, meaning the number of entries in @a. perldoc -f map perldoc -f join perldoc -f rand My tip for cases where you get a working solution you don't understand fully: a) Try to find out what "belongs together" (imagine '()'s) b) Try to break the solution apart according to the findings in a) c) examine the parts: print them out, dump them with Data::Dumper, modify them, read the man pages d) put them together again, eventually one by one part, using examination techniques as in c) Hope this helps!
