Dave,
Here is a Jscript that I use to run AFL
scripts one after another. To be precise, it’s actually a
hacked up version of what I use. (My “production”
script does logging and some error checking). It shows how scans
and explorations can be chained together. It loads each AFL and its
associated parameters and then executes the AFL.
To execute multiple AFL scripts, just run
the AFL scripts one after another like I have here. If you wanted to be
slick, you could instantiate the Broker.Application and Analysis once and then
loop through changing the parameters.
You would need to edit this to your
parameters (paths, files and other parameter settings) and then save it to a file
in the ..\Scripts folder. The file should have a “.js”
extension.
You can call this Jscript file from the AB
Tools Menu or you can schedule it to run using the Windows Scheduler.
Regards,
Dan.

Hi Dan,
Thanks for the code below. You
wouldn’t happen to have any scripts that will automatically run a number
of AAs in a batch mode do you?

Brian,
Add this at the top:
CategoryRemoveSymbol("", categoryWatchlist,
1); //Watchlist = 1
…
//Some criteria code
…
//Add Symbols to Watchlist 1
if (bCriteriaIsMet)
CategoryAddSymbol( "" , categoryWatchlist,
1); //Watchlist = 1

results handling (w/o Batman)
I used to have a small script
that would automatically take
exploration results and put them in a specific
watchlist. I have
looked at Batman but I think that might be
overkill for what I need.
Only other functionality that would be nice is
such a script would be
to automatically delete the contents of the watchlist
prior to
repopulating it.
Anyone got this script handy? Mine got lost in the
shuffle awhile back.
Thanks in advance!
Brian
