ILE Questions

I already sent it with a blank subject. Please ignore
it if you've already read it.

Hi All,

Please pardon me if these sound too trivial but they
have really puzzled me.

1. Can a RPGLE program call another RPGLE program
through the use of CALLP? They both run in the
different Activation Group.
2. What's difference between CALLB and CALLP? Can they
be used in place of one another?
3. Are ExtPgm and ExtProc used for "just" the renaming
purpose or there is some other very useful features
associated with them?
4. Why can't I have "Value" parameters for main
procedure? Any logic behind that?
5. And lastly(scoped to this mail only) why there is
no F-Spec in Subprocedures?

Thanks a lot for bearing with me.

Rajeev.
