Hi Sang-ki,

You can use the "sprinti" function to format your integers and to
force a leading "0". To get "01" try this:

   i = 1
   s = sprinti("%0.2i",i)

For more examples, see the "Examples" section at:

   http://www.ncl.ucar.edu/Document/Functions/Built-in/sprinti.shtml

You could also do something completely different:

    if (i.lt.10) then
      s = "0" + i
    else
      s = "" + i
    end if

This is a bit kludgy, however, and I wouldn't recommend using
it in a "do" loop. I included the above so you can see the
sneaky method of quickly converting an integer to a string with:

      s = "" + i
