Well, I have to correct myself, since had to look through the code recently. ADD_CRE_ITEM does not use the cre module in the current implementation.that's good to to hearThis has changed a bit.
WeiDU now has a cre module, which is able to deal with non-default ordering. (It reads the stuff into structures, modifies these and outputs the cre in default ordering.)
But nearly all the other commands that deal with CREs use it.
