bit operations happen normally on unsigned integers, I'd say in >90% of the cases (at least) And I've already shown two instances of perldocs demonstrating exactly that pattern. > in a PV ? in an IV ? in an NV ? I reckon IV is an integer value ... please explain the rest° in this context, my perlguts are aching ;-) And the OP will most probably only know "scalar".
Cheers Rolf °) OK looking up in "Advanced Perl Programming" (sic) > A scalar value (SV) contains the value of the scalar, a reference count, and a bitmask to describe the state of the scalar. The scalar may be an integer value ("IV"), a double ("NV"), a string ("PV" for pointer value), I can't see how this is relevant here.
updateI mean: If someone asks how best to hold a hammer, do you complain he didn't tell you which alloy the nails are made of and where the original ore was mined? Seriously?
