Yes, you can use DFSORT's IFTHEN/OVERLAY function to do that.

If you're not familiar with DFSORT and DFSORT's ICETOOL, I'd suggest reading through "z/OS DFSORT: Getting Started". It's an excellent tutorial, with lots of examples, that will show you how to use DFSORT, DFSORT's ICETOOL and DFSORT Symbols. You can access it online, along with all of the other DFSORT books, from:

www.ibm.com/servers/storage/support/software/sort/mvs/srtmpub.html

If you need more specific help, tell me the starting position of the 'BE' field in your input records, and whether your VSAM input records are all the same length (fixed length) or can be of different lengths (variable length).
