That has always
been TJ's position.
But from my perspective, using ATC for simple
"Counting" functionality
when I want to do quick counts of various
conditions that exist within
a Watchlist or Group is usually more trouble
or effort that I am
willing make where ATC's are concerned.
Why not
simply add a new variable type that is initialized with each
execution of
an Explore and then 'persists' throughout the execution
of the entire
Explore so that you can display the various Counts of
whatever you want
without having to use the more complex Composite route?
Maybe there is
something too complex about establishing a new variable
type of this nature
in AB that I don't comprehend... and then maybe not.
