[amibroker] Re: How to write to a file with a dynamic name including a date

["Mike" <sfclimbers@xxxxxxxxx>]

I haven't tested this out, but, the same principle should apply. If 
you are only running the script once a day, with each day's new data 
each time, then you can try something along the lines of:

filename = "d:\\newfold\\myfile" + LastValue(Year()) + LastValue(Month
()) + LastValue(Day()) + ".txt";
fh = fopen( filename, "a");

If you run multiple times a day, you will clobber the file of the 
current date each time. In such cases, you might want to append the 
time to the file name too (e.g. Hour(), Minute(), Second()).
