How about if shops start changing COBOL build processes today to use PDSE
datasets for COBOL V4 (or COBOL 3) programs?
Step 1 would be to allocate new PDSE datasets for each zone of load libraries
Step 2 would be to add the new PDSE dataset(s) to load library concatenations
 where needed. If put first it would guarantee access to new programs.
Step 3 would be to change build processes to link old COBOL programs into PDSEs.
Step 4 would be to make sure this works for all systems and that old 
(unreachable)
 programs get deleted from PDS datasets
Step 5 from time to time, move needed load modules from PDSs to PDSEs until all 
are
 moved.
Step 6 when all code has been moved, the only programs in PDS should be
 unused, and the PDS datasets could be deleted

  If this plan was used, the COBOL V5 PDSE requirement would not be disruptive.
My question, is it do-able?
