I have the same problem as Mirko and I think the problem might be the
length of the -at()- option.

Below I have created an example (with huge names for the variables where
you can see the warning message.

Does anybody have a suggestion?
It looks to me like you have problems once the # of characters in the at specification exceeds 244. 244 is the limit for "length of string in string expression", so maybe that limit applies for options to commands, or is otherwise somehow complicating things.

What puzzles me, though, is that in the original example, it seems the at option would be well under 244 characters. I wonder if Mirko gave the exact commands he had typed or had simplified it?

There might also be some sort of problem if a string containing all the var names gets longer than 244 characters. In his regoprob command, Mirko might just try putting the z vars first, so that their names will fall within the first 244 characters of all the var names.
