PL/I is an application programming language where the compiler has knows enough to give you everything you need to debug the problem. System level programs are very different and often require a dump. Multi-tasking requires dumps because you need to know about tasks PL/I can't possibly know about. PL/I doesn't know about CB chains so you may need to find out how you arrived at the wrong CB. If there is a storage overlay, then your program may not be the cause. Regards, Jon.
