Thanks for being awesome!!! Man, I searched all over for solution to this before asking.

I just wanted to say that the problem I was having was resolved using the
SCRIPT-CALL given above. I used the
SCRIPT-CALL in a
CONDITIONAL BRANCH of a
PARALLEL PROCESS. If the
SCRIPT-CALL returned
TRUE, I had it turn
ON a
SWITCH. When the
SWITCH was
ON, my "hostile event" would no longer allow the actor to talk to it.
For anybody having trouble checking for
ALTERED-ALIGNMENT with this
SCRIPT-CALL, I would recommend making sure your event's alignment group is
NOT set to
NEUTRAL (as stated in the manual). Also make sure that the
ALIGNMENT GROUPS (allies, enemies, NPCs, Guards, etc...) are all set up right (using the config program).
The other problem mentioned above, calling the SETUP_GROUP, I have no idea on, but it doesn't seem to be affecting my game.
Also, make sure you're currently using the latest version of Blizz-ABS.
