IIRC BP function results were either passed back in registers, an fpu
register, or as a double word stack entry (in the case of strings). While I
haven't found an explicit explanation, I would expect that neither records
or array types could be used as function result types. I wouldn't be
surprised if sets, at least those with a base type of cardinality > 32,
were also disallowed.

Add a Var parameter of the appropriate type and turn the function into a
procedure. Or, as another poster suggested return a pointer type.
