Hi Graham,
you would need to put the ABtool.DLL into ABs
"Plugins"
subdirectory and load this new plugin (all DLLs there
are
usually loaded automatically at AB start. To <FONT
face=Arial>see which
plugins have been loaded use menu
Tools/Plugins).
The AFL plugin DLLs offer some special or additional
functionality which the user can
use in his AFL scripts.
If you think the functionality it
offers is of some use for you
then let me know <FONT
face=Arial>and I'll send you a copy of ABtool.DLL
beta version.
So, regarding your question about the script below: it
is
to demonstrate the use of the new
functions ABtool.DLL offers.
You would need to load it into the Automatic Analysis
window,
set your scan parameters (see note) a<FONT
face=Arial>nd change the
watchlistnum and the name of the filename to yours,
and
press "Explore" to run the script.

partially answer my own question by asking another. Perhaps it

<FONT face="Times New Roman"

<FONT face=Arial color=blue

there some way to access a text file from within a loop?
The text file could contain all of the tickers that I want to access in the
loop. Or... do I need to write a dll to do
this?

<FONT face=Arial color=blue

time has come for me to find a better way of looping through thousands of
foreign files.

<FONT face=Arial color=blue

<FONT face=Arial color=blue

the "foreign" statement would accept a stockID number instead of a ticker,
I could probably make a decent loop to do the job. But, alas,
that's not how it works.
