Please allow me to add my 2 cents.
On a project in 2005, I have tested and verified that the behavior you
note below (Foxdraw is performing the action on the PAKCIN as a whole,
and not on an individual bit) is correct.
This was tested on FoxDraw V10, I/A V8.2 on a P92 w/s.
At the time, I had entered a CAR on the subject (CAR 1006559).
Subsequent testing and response from GPS (TAC) confirmed this.
By using B1 as a test bit, the bit extension seems to work because the
whole PAKCIN parameter evaluation goes from 1 to 0 and back to 1 when
toggling.
Your suggestion for a follow-up test would defeat this and prove the
theory.

Ronald,
1) I appreciate the response.
2) Can you check one more thing.
=
I'm sorry, perhaps I didn't go into enough detail, but if you
create =
one fill object to C:B.P.B4 (or whatever) and another to C:B.P.B3 =
they will both fill and unfill together. Anytime any bit is set (the =
pakcin is non-zero) all the fill items (or visibility, or any =
discrete operation) will exhibit the TRUE condition. At least that's =
what we are seeing. So it looks to us like Foxdraw is performing the =
action on the PAKCIN as a whole, and not on an individual bit.
Let me know.
Thanks,
David
