Don't thank me too soon. :-)  Your question is equivalent to me going to SAS-L and asking someone to teach me SAS macro language.  You need to provide more information about what your task actually is.  Where are these file names that you want to process coming from?  What do you want to do with them?

The basic approach would be to put the file names in a list and then pass the list items one at a time to your function.  But how to do that really depends on what you are trying to do.  You might also read the posting guide listed at the bottom of every posting.
