Dynamic field resolusion in Xlate

Hi all.

I know it is far fetched but I would like to hear if any one tried something like this.

Problem at hand:

key/value pairs coming in incoming OBX message.

I have a lookup table to identify a key and returning fieldNumber for my Z segment.

I know that conventional metod to do next step is, to create an if statment and then store value.

Which is a big issue if you can recieve large number key/value pairs

Question:

Is any one managed to dynamicaly generate a destination field in Xlate that was derived from variable?

key|value

color|red

shape|circle

location|aruba

table mapping

color     -> 1

location -> 2

shape    -> 3

result should store

color value in ZF.#1.[0]

location value in ZF.#2.[0]

shape value in ZF.#3.[0]

{ OP COPY }

                                   { ERR 0 }

                                   { IN @value }

                                   { OUT {{0(0).ZF.#@retval.[0]}} }

Thanks.
