Sure. That's exactly how ByRef works.
Dim foo As Ptr, bar As someStructure
bar = foo.someStructure
that's fine if we want a copy of the structure values, but not if
we need to
keep playing with the original structure "in place"
Then just keep playing with the original structure in place, and
don't copy it into another structure variable. My example just showed
that the lookup operator works with Ptr using a type name. If all you
need is one field of the structure, keep on chaining up dots and
field names until you get where you want to go.
