note kingpin007 Ah okay, thank you so much for that! What a silly mistake I didnt even realize that. And yes, i had actually used grep/map in my code as well to get the same output <code> @number = qw(1 2 3 4 5 10 11 12 13 14); @num = map ($_ *$_, (@number)), "\n"; @square = grep ($_ >=100 && $_ <=200, @num); print "Obtaining square values using map/grep: @square \n"; </code> I just wanted to learn how to do it through a foreach loop. Thanks again for the quick response and help! :) 996795 996796
