The issue is not foreground vs background. The issue is that MVS and its predecessors have never provided a service to change TCBJLB after a task has been attached, so there may be ways in which programs assume that such a change will not occur. We believe that it would be dangerous to change this paradigm, so IBM does not, and will not, provide such a capability.
IBM does provide products which use TASKLIB on ATTACH, such as ISPF, and TSO commands issued from READY after a TSOLIB command. Jim Mulder z/OS Diagnosis, Design, Development, Test IBM Corp.
