Hi,

I would like to split a string into sets of characters without the help of a delimiter. For example if I have a random string like this one:
my $str = "1101111000110000001110110111";
I'd like to split it into sets of four characters, so 0-3, 4-7, 8-11, etc and then process them in a loop like foreach.

How can I do this?
