Dialog box for datafile.save

[AndyField]

Hi - sorry another question. :-[

I've been able to save and load a datafile that saves an array to a user's PC.

However, I want to be able to let the user choose a filename / trigger a windows dialog box.

The code:
Datafile.save("\\C:data.txt","data")
saves the data array to the C drive.

The code:
Dialogs.filesave(" etc. etc. triggers a dialog box.

Can I somehow combine the two to save a datafile via a dialog box.

var filter = "Data files(*.txt)|*.txt|";
var filename = Dialogs.fileSave(filter, ".txt");

if (filename) 
{
    DataFile.save(filename, var0, var1, ..., varn);
}
