What I need is a sort of permutation, but limited, and given sets. For example, say I have: 

@one = qw{C A T};
@two = qw{D O G};
@three = qw{B I R D};

I want to be shown as results:

CDB
ADB
TDB
COB
COI
etc...

So, I always want an element of the first set first, the second second, and third last. I don't want:

DAR
BOT
etc...

I have been trying to hack some permutation code to not give me evert combination possible, and to only give me combinations in the order I want, as well as accepting sets, but so far to no avail. Anyone know of something which does this, or have a good solution? The available permutation modules can't seem to do this, or if they can it isn't obvious to me. Even some decent pseudo-code would help me on this one.. thanks.

Cheers,
KM
