Hi Herman,
Did you ever make code for the following application - using mentioned
functions in the UKB - or can you give me a link to code for this kind of
application ?
Persistent variables can also be used to save ticker-specific system
parameters. For example, you could run an optimization and save the optimized
parameters in a Persistent Variable encoded with the Ticker's name.
Regards, Ton.

you can use PersistentVariables, they can be read from any programming
language because they are saved in small files.
see http://www.amibroker.org/userkb/2007/04/24/persistent-variables/

As usual you're the man. The following is partial code that I am using
/* retrieve automatic analysis object */
AA = AB.Analysis;
/* backtest over symbols and all quotes*/
AA.ClearFilters();
AA.ApplyTo = 0; // use symbols
AA.RangeMode = 3; // Last Day
//AA.RangeN = 1; // Last Day
FromDate = new Date;
/* year, month-1, day, hour, min, sec (required by JScript date
constructor) */
ToDate = new Date; // current time
/* getVarDate is required to convert from JScript Date to
OLE-automation date */
AA.RangeFromDate = FromDate.getVarDate();
AA.RangeToDate = ToDate.getVarDate();
AA.LoadFormula("Z:\\amibroker\\Formulas\\1Production\\O2.afl");
AA.Explore();
AA.Export("Z:\\Amibroker\\CSV FILES\\O2.csv");
AA.LoadFormula("Z:\\amibroker\\Formulas\\1Production\\O3.afl");
AA.Explore();
AA.Export("Z:\\Amibroker\\CSV FILES\\O3.csv");
..
..
O2.afl, O3.afl &... Ox.afl are identical except for different value for
a variable. So rather than maintaining all these afl files (O2.afl, O3.afl &...
Ox.afl) I want to loop thru variable values in jscript and pass the variable
value to Ox.afl. something like:
For (var = 1 to 100)
AA.LoadFormula("Z:\\amibroker\\Formulas\\1Production\\O2.afl");
AA.Explore();
AA.Export("Z:\\Amibroker\\CSV FILES\\O2.csv");
Where diferrent values of var create a new explore and then is exported
to Ox.csv

Are you asking if you can have a stand alone, external jscript that
drives AmiBroker to fire off multiple Explores one after the other (i.e. using
OLE Automation), altering AFL variables along the way?
Or, are you asking if you can have jscript embedded in an AFL script
that fires off multiple Explores one after the other?
If the former, you can do any of the following:
1. jscript first writes desired values to file on disk, AFL Exploration
reads values from disk file.
2. jscript first runs minimal AFL script, whose sole purpose is to set
static variable(s), AFL Exploration references static variables
3. jscript first modifies .AFL file on disk, AFL Exploration runs
normally.
