Mike, I just responded to your other reply as I missed it for some reason. Thanks again for this. I will certainly use it!!
I will leave my post for help in creating an afl within JavaScript. I want to: (1) create an afl from within JavaScript; (2) feed to this something that changes like the watchlist number, a file name, a ticker name; (3) run an exploration on this afl; (4) delete this afl when done. Help with this will help me to do a bunch of stuff that I want to do in JavaScript. In time, I will be able to do this stuff better, but for now this "create an afl within JavaScript" will help a lot.
