Thomas, STEPLIB from CBTTAPE works, I've tested it but its not supported/recommended. There was a discussion about DYNAMIC STEPLIB last year and Jim Mulder wrote: The only supported mechanism in MVS for adding to the module library search order within as address space is an ATTACH with a TASKLIB. This is the only supported way to set TCBJLB. Any program which modifies TCBJLB in an existing TCB is wrong to do so. I would recommend against having any such program installed on your system.
