Dear Jared, You can make it part of the loop with something like: for i=1 to 10; outpr='IMFITOUT'!!char(i); go; end this will give you an outprint file with the name IMFITOUT1 to IMFITOUT10. You can do more fancy things too, but, of course, the for loop has to fit on an 80 character line. See chapter 12 of the AIPS cookbook for more information. Cheers, Amy
