Re: 1 of 10 Is it possible to create a command that will present different options based on the value entered initially?

I have a general question on a very similar project: In today's modern

Booth,

We don't swivel away from commands and toward service programs, or
vice versa. They are very different tools, and there isn't much
overlap between what they do. Nor are they mutually exclusive. Neither
one is "more modern" than the other.

A service program is a library of ILE-linkable code. The point of it
is to be a mechanism for modularity and code reuse. It's only of use
to programmers, particularly ILE programmers.

A command is something that can be invoked from CL, either
interactively at a prompt, or in a CLP. It could be useful to
programmers, but it's also something that system administrators or
perhaps even end users interact with. Even to the extent that it's
useful to programmers, it's at a different "level" than service
programs.

Indeed, a command is just a wrapper that accepts parameters and passes
them to an almost arbitrary program. That program could well involve a
service program in its implementation.

So, I have to say, I don't think the question even makes much sense.
