Yeah, I'm currently doing an open so I can parse the input
one line at a time with a while statement (just like how it

that'll provide similar functionality without having to call
an external program.

\_ that important!
DISCLAIMER:
These are MY OPINIONS ALONE. I speak for no-one else.
FYI:
perl -e 'print $i=pack(c5,(41*2),sqrt(7056),(unpack(c,H)-2),oct(115),10);'
