You could have achieved the same thing with Inz(*LIkeDS) alongside the
LikeDS keyword. This has the benefit of copying any and all
initializations from the cloned DS.

Thanks Buck. That seems to have fixed it!
I applied the same fix to my "real thing" module, and it appears to

be behaving as well.

Many thanks to Bob, Chuck, and Stuart as well.

Right, so you're passing the data structure ParmsIn and it is not
initialised. Put an INZ on that and see how it works. INZ on the
'likeds' doesn't inherit up to the 'liking' DS.
