Yes:

my @array = unpack '(A4)*', $string;

Thank you very much, I had overseen this option of unpack. Yous answer is really useful for me.	[reply]

Just FYI: You refer in several places to wanting groups of five characters, but `'A4'` or `'(A4)'` will give you a group or groups of four* characters, trailing-space padded if necessary.	[reply] [d/l] [select]
