    Joe,
      I won't reply the way you suggested, but rather by saying that *IF* one is in
    an IBM mainframe environment, what this thread actually reminds me of is the
    existing SHARE requriement,

    "SSLNGC0313587 New LE Callable Service to get (various) Program Names
        ...
    A new LE callable service (with capabilities well beyond CEE3GRN) should be
    created to obtain various program names. This should include options to obtain:

    - The currently executing program's name
    - The name of the program that "activated" (Called, Invoked, whatever) the
    currently executing program
    - The name of the program at the "top" of the current LE "enclave"
    - The name of the program at the "top" of the current LE "thread"

    For each of these, sub-options may be required to provide information such as
    - Any "alias" by which the program was entered
    - Any "long-name" (with mixed characters) as supported by the Binder
    - Any Entry-point name when other than the modules name

    Finally, although not necessarily a part of this callable service, it would also
    be desirable to be able to obtain the "data set name" (HFS, PDS, PDSE, LPA
    member, or whatever) from which each of these entities was obtained."
