It sounds like SuperCard has you specify the WDEF resource ID and the
variation code independently. (A WDEF can support up to 16 variation codes,
each one a variation of the basic window appearance coded by the WDEF.)

In Rev and MetaCard, you instead multiply the resource ID by 16 and add the
variation code as a number between zero and 15. For example, to use
variation 6 of a fictional WDEF whose resource ID is 20, you'd specify (20
* 16) + 5 = 325:

  set the decorations of stack "Whatever" to 325

It sounds like the SuperCard syntax, or even better something like "set the
decorations of window to WDEF 20 with variation 5", is more elegant - maybe
something that could be added as an enhancement at some point. But the
functionality is the same, you just have to remember the little formula
above.
