Allow to execute Commands directly from RPG without the QCMDEXC interface

Similar to EXEC SQL, to do EXEC CMD or EXEC CL.

Use Case:

    IBM does not intend to provide a solution to this request at this time, so it is being closed. Even if this enhancement were to be delivered, RPG would not be able to process commands with RTNVAL(*YES) parms. The Integrated Language Environment of IBM i allows programmers to combine modules compiled from different programming languages, so programmers can easily add CLLE modules to their programs to accomplish tasks that need CL's support for commands.

    If RPG provided this feature, it would be implemented using an API (system(), or QCMDEXC, or QCAPCMD). It would not be able to handle commands like RTVSYSVAL that return values.

    Of course this will be diferent!

    Imagine if in a CL PGM we would have to run all comamds only through the QCMDEXC service. We got used to run a command not as a string, but part of the language, and that is so beatiful, it is even hard to imagine how could we be without it.. Why not have it in RPG.

    Besides that, the QCMDEXC service cannot return values, it cannot be issued for RTVSYSVAL, RTVMBRD, RTVMSG and many other commands.

    How would this be different from the QCMDEXC service currently available?
