But your unpack routine doesn't seem to work correctly.

It does: 

$s = 'a' x 10; 
print join( 'B', unpack '(A1)*', $s ) . 'B';;
aBaBaBaBaBaBaBaBaBaB

But not with nulls. The template would have to be '(a1)*' in that case.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
