Create a 512 bit decoder

[Andy_P 7]

The built in "Decoder" instruction on the NJ controller has the ability to decode up to 256 bits. I'm trying to make a decoder function block that handles up to 512 bits, but brain-freeze and Friday afternoon means I'm struggling a little. Can anyone point me in the right direction? Thanks for any help.

Use a loop to advance through each index?
