Some IBM Program Products had source code available from the earliest days. For example, the PL/I Optimizing compiler had source code that was simply orderable as an option. The same was true of ACF/VTAM and many other quite mainstream products. Program Product versions of JES2, and of course VM, continued for a long time not only to have source available, but to be source maintained. But when the OCO is a Good Thing meme got entrenched in the early 1980s, new IBM code - priced or not - mostly did not have continued source availability.
