I think that what you want to do isn't so hard, but your code has a few oddities:
- day3 is already a string - you don't need to convert it with the day2 line
- ok, day1 should be an integer conversion of the string value, so...
- what is that 1x1 array for? In any case, day1 and day are integers... there's no need to use reads here.
Hope that helps you on the way,
Greg

Hi,
as far as I see, there might be a chance that your day and year
variables are no strings.
Try something like:
filename =
STRING(year,FORMAT=('I0'))+'_current'+STRING(day,FORMAT=('I0 '))+'.dat'
Please read manual on STRING and FORMAT!
HTH,
Kai
