Re: qsh: Avoiding "Press ENTER to end terminal session."

Hi Paul,

That's someone's attempt to dumb-down the difference between QShell and PASE. I see what he's trying to say, there... though I think the phrasing is misleading in some ways.

Neither QShell nor PASE is "actually" Unix. They are both components of IBM i... they run on IBM i (formerly known as "OS/400") not Unix.

The major difference between them is that PASE can run programs that were compiled for AIX (without recompiling.) You can compile software on AIX, save it, then restore it to IBM i and run it in PASE.

QShell on the other hand runs programs that were written in a Unix-like way, but are compiled for the native IBM i environment. (via the ILE compilers, for example.) (Though, if PASE is installed and QShell detects that you're trying to run a PASE program, it'll load PASE and run it for you automatically...)

I don't see what it has to do with this discussion, however. Was there a particular point that you were responding to that I could try to correlate your post with? Or did you forget to change the subject line of your e-mail? Or... why did you post this?

It's not really UNIX, it just acts like it is.

"PASE is a "real" UNIX-it is actually AIX. It looks similar to
QSHELL, but doesn't have some of the limitations built in to
QSHELL."

To use QSHELL, use command QSHELL or QSH.
To use PASE, CALL QP2TERM.
