I'm not sure I understand what you're trying to do. An example of your input records and what you expect for output for various cases would help. However, if you're looking for something that will find and replace multiple consecutive characters like TRAN=ALTSEQ does for one character, DFSORT now has that capability. Find and replace is one of the new features in z/OS DFSORT V1R5 PTF UK90013 (July, 2008) which is described in detail at: www.ibm.com/systems/support/storage/software/sort/mvs/ugpf/ If you install that PTF, you'll be able to use FINDREP to do various types of find and replace operations.
