using SYMBOL..WATCHLIST..New Watchlist must be used to create the new
style watchlist. I do not see how to do the logical equivalent of
SYMBOL..WATCHLIST..New Watchlist strictly using AFL for the new style
watchlist. For distribution purposes, I would prefer to not have a
client have to manually enter potentially hundreds of watchlist names
using the Symbol menu.

according to debugview instead of the next available ordinal index
number. Obviously, the CategoryFind function is used to retrieve the
ordinal number of the watchlist for parameter entry into the other
Category... functions in AFL.

this do-able? I have heard that you can code a workaround using FSO
(file system object) and something about maintaining the index
yourself. Unfortunately, I did not see any code posted. It seems
this would be best done by TJ so the implementation of watchlists
would not be broken in case additional enhancements were made. Also,
the ability to delete a watchlist is needed from AFL so that you do
not have to predict ahead of time which watchlists need to be created.
