I'd call that an implantation detail. The compiler would have to be smart enough to deal with it, and possibly require the parms in those cases.

Subject: Re: 2nd & 3rd parm on %dec()
Yes because not every expression that uses %dec() or the right hand side looks like:
fielda = %dec(fieldb)
What about those instances where %dec() is part of a more complex expression? I am sure you can conceive of one complex enough that the precision and scale of the result will not match that of %dec(). Also what
about:
evalh fielda = %dec(fieldb)
In this case the scale of fieldb needs to be larger than that of fielda or the evalh will be meaningless.
