Isn't a big obstacle on z/OS the fact that TSO doesn't have a generalized interface for invoking a "command" in an arbitrary scripting language and then providing it with a command processing (and/or ISPF) interface? What if the TSO command interface that handles REXX/CLIST could recognize shebangs to support other script processors, which would be local-spawned in the TSO address space and be given a TSO Command processing environment? Who knows, maybe get crazy and allow TSO command/script processing from zFS. With mixed case > 8 characters!
