I was able to solve my problem thanks to
Tomasz's example in the "readme" file documenting the changes for AB
version 4.24.0. Although I know nothing about Jscript or OLE and had no hope of
being able to understand it, the example Tomasz provided was clear
enough that I only had to modify his example a little to suit my need. I'm
including my modified file so that others who might have similar needs may
benefit. To modify my file to suit your particular need, you need only
change the path in the AA.LoadFormula command to the path to your AFL scan and
change the AA.Filter command to whatever "market", "group", "watchlist", etc.
you wish to scan on. Repeat the section between the /*********/ as many times as
you have different settings to work with. Also, I added the "Composites.js"
file as a command under Tools/Customize so that updating my composites is
now a one click operation. Is this a great program, or what?
