Thanks, Mike. That's a great help.
Yes, there was some junk in my original code. I cobbled it together
from other examples found on this group, and I didn't quite know what
I was doing.
Thanks also for letting me know of the ability to run from the command
line window. I had not even thought of that, or was aware it could
work that way. Do you have any online Jscript tutorials that you could
recommend, specifically geared towards automation? I found some
general purpose tutorials, but want to focus just on automating stuff
like this.
I am still a bit confused why your code runs fine (all 100 opt steps)
when run from the command line, but only does a single opt step when
run as an AFL that simply calls the identical jscript routine.
