But since $i is not used: `use strict; use warnings; my $number = 8; for (1 .. 20) { print "present value of the number is:", $number++, "\n"; } # or print "present value of the number is:", $number++, "\n" for 1 .. 20;` [download] make the number of iterations clearer and make it clear that the value of the count is unimportant.

More merging ... `use 5.10.0; use warnings; my $number = 8; say "Present value of number is: ", $number++ for 0 .. 19;` [download] Enjoy, Have FUN! H.Merijn	[reply] [d/l]
