Re: vec and array parameters

I ran into the same thing with seek when writing this poem. If there is a reason you have an array instead of two separate variables for OFFSET and BITS, and you're going to call it a lot, you can write a wrapper like I did:

sub my_vec { vec($_[0],$_[1],$_[2] }

or just call it like vec($vec, $params[0], $params[1]).

I thought of that too, but if you try to use my_vec on the left side of an assignment, you get: `Can't modify non-lvalue subroutine call at testvec.pl line 10.` [download]	[reply] [d/l]

Oh, then just make your sub an lvalue sub like so: `sub my_vec : lvalue { vec($_[0],$_[1],$_[2]) }` [download] Caveat scriptor, I didn't test this at all and I'm sure you need a modernish perl for it to work. duff	[reply] [d/l]
