- No, you still have multiple processes. You lose multiple *sessions*.
- You can't DosStartSession another program. You *can* DosExecPgm another
- fullscreen program (meaning it runs in your same session)...this is what
- CMD.EXE itself must do to run your app (in this environment). You also can
- have detached processes (I think ?) which by definition do not require
- sessions.
-
- In short, I suspect (without really knowing) that aside from GUI-ness,
- PMSHELL gives you the Session Manager.

- Actually, app A *might* support running app B in the middle of A (e.g. if A
- lets you shell out to the command line). It is up to the app. The point is,
- all your processes share the common screen group (session).

- Really ? You can start DOS sessions in this environment ? Maybe my
- information is outdated.
