The Logic Manuals for OCO components continued to be maintained for a while, available only internally, with a lot of overblown security requirements. I still have a cabinet full of them in my office. But the most recent updates I have were from SP5.1.0, and they were discontinued after that. My recollection is that the costs to write, print, and distribute them was the reason for their demise. Jim Mulder z/OS System Test IBM Corp.
