Bert,
The solution proposed by Howard using fopen/fputs would look something like the following (only briefly tested, and not necessarily the most efficient implementation):
myCSVFile = "c:\\Temp\\Exploration.csv";
if (Status("stocknum") == 0) {
//
// Open file, overwriting any existing file, and write the header
//
fh = fopen(myCSVFile, "w");
if (fh) {
// Make sure header matches same order as AddColumn statements.
fputs("Ticker,Date/Time,Close\n", fh);
fclose(fh);
}
}
Filter = 1; // Set to whatever value you want.
AddColumn(Close, "Close"); // Add whatever columns you want
// Open file, appending to any existing file, and write the data.
// Make sure this comes after the setting of Filter.
fh = fopen(myCSVFile, "a");
if (fh) {
indices = BarIndex();
firstBar = LastValue(ValueWhen(Status("firstbarinrange"), indices));
lastBar = LastValue(ValueWhen(Status("lastbarinrange"), indices));
dates = DateTime();
symbol = Name();
for (i = firstBar; i <= lastBar; i++) {
if (Filter[i]) {
// Make sure output matches same order as AddColumn statements.
fputs(symbol + "," + DateTimeToStr(dates[i]) + "," + Close[i] + "\n", fh);
}
}
fclose(fh);
}
You can improve upon the above by accepting the file name as a parameter, etc.
I don't have time at the moment to throw togeather an OLE/JScript solution. But, if you particularly want it, I can post a follow up later.

I did read Barry Scarborough's Export EOD doc and afl. This is different. I saw Mike's comments about OLE and yours about OLE/js. Have written some very simple js to control running afls. Actually, I got an example from a friend of mine and simply cut and paste it to do what I need. So, I have "some" knowledge about js. Enough to read and understand it. In any case, if you or someone has a simple example than this would be great. I have also ready Harry's comments and tried using fopen and the like. Not giving up. Will keep at it, but if someone has example of exporting exploration then maybe I will get an "ahh, that is what I am doing wrong" moment. Thanks.
