Joe,
I copied your code as you show below and
ran it. It didn’t work. So I looked at my settings for the
AA.
I had it set to Use Filter and that is
pointing at Watchlist 4. But the code is pointing to WL#1, so I changed
it to All Symbols without thinking (much) and hitting the scan button, about 70
symbols showed up in the results window before I could stop the
scan. Well, those symbols are gone. Shouldn’t be
a problem getting them back as they are retrieved from the TC2005 DB.
So I changed the code to delete WL # 4 and
changed back the filter setting to include WL # 4 and ran the scan again.
It worked.
Based on what just happened, it is
suggesting that not only do I have to specify in my Scan code, I also have to
point to it via the filter setting?

I just clipped this out of a
formula that works and based on an example that Tomasz wrote and is in the help
documentation.
I don't why it doesn't
work...Could be you're missing the Return statement from the
function.
Run this as a SCAN, select Refresh All to
see your WL No. evaporate. Make sure it's the one you want to get rid of.'

Hi folks,
I can't seem to get this to work. Here is my
code:
// Exploration code to clear a watchlist
function ClearWatchList(_watchListNumber)
{_toClear = CategoryGetSymbols(categoryWatchlist,
_watchListNumber);
for(i = 0; (symC =
StrExtract(_toClear, i) ) != ""; i++)
{CategoryRemoveSymbol(symC, categoryWatchlist, _watchListNumber);}
}
ClearWatchList(4);
Filter=True;
I read in the help files that the
"GetCatagorySymbols" was changed to
"CatagoryGetSymbols" and so I am using
that Function.
It is probably something simple.
I am trying to run the code above as a simple
exploration to clear out
a single watchlist. The loop code below will
be next. Then I am
thinking of using the #include function to add it
to a number of my
explorations. My thinking is that this small
piece of code will be
easier to manage from one file than if I copy and
paste into all of my
explorations.

is it possible to add scan results to wathlist with AFL
programmatically? I have to do "add all
results to watch list" all the
time at this point.
