DFSORT's ICETOOL is a fully documented, fully supported feature of DFSORT, if I'm not mistaken ICETOOL has been with DFSORT since 1991. If you can use DFSORT you can use ICETOOL. Below link might provide a better understanding of ICETOOL
DFSORT's ICETOOL is an extension of DFSORT that allows you to do many tasks more easily than you can using DFSORT alone as in this case. So I can't imagine why the people at your site are forcing you to do it with DFSORT instead of with DFSORT's ICETOOL.
Your site's license for DFSORT includes ICETOOL, so why wouldn't they want to take advantage of it? ICETOOL HAS been a part of DFSORT since 1991. It is proven technology and after having been around for almost two decades is certainly not new or risky. I'd suggest you ask whoever it is who says you can't use it what their justification is for not getting the most out of a product they're paying good money for. You can point them to the complete documentation of DFSORT's ICETOOL on IBM's official publications website at:
