write/read file

[philtong]

Is EFS able to read from/write to a file?
If yes, is there any documentation and samples out there.
Thank you in advance.

yes u can

here is what i do..

function main(){

// FILENAME WILL LOOK LIKE ES-MM-DD-YYYY.txt
Log1 = sym+"-"+ my_month + "-" + my_day + "-" + my_year+".txt";
f1 = new File(Log1); // PUT IT IN FORMULA OUTPUT
f1.open("a+");

if(!f1.isOpen())
{
debugPrintln("*** Couldn't open TRADE LOG!");
}else
{
debugPrintln("*** "+sym+" TRADE LOG OPEN");
}

f1.writeln(".Short.Reversal.Cancel.All");

// CLOSING THE LOG FILES
if(f1.isOpen())
{f1.close();}

Some amount of documentaion is HERE

fileformularef.doc is the file you want.

Also, there are formula example of how to use this in your local formula's directory. I think it is under "other", but I don't have eSignal running where I am right now to verify.
