No, it is not reversed. As elsewhere in the world, the server
LISTENs for a connection; the client requests to CONNECT.
It has nothing to do with size, importance, or influence.
As a parallel, when President Clinton (with an entourage
of bodyguards and reporters) walked into McDonald's
and ordered a hamburger, Clinton was the client; the
low-wage clerk behind the counter was the server.

You're welcome.

Curses and X11 are not supported with the Enhanced ASCII
option in effect (note the word "ASCII" in the Subject: line.
But the last time I tried it was several years ago.) I haven't
tried sockets with that option (but sockets should be a
prerequisite for X11).
In:

B.3 Library function support
Table 62 shows all the z/OS XL C/C++ Run-Time Library functions in
alphabetical order, their support of Enhanced ASCII processing and
their support of Preinitialized Environments for Authorized Programs.
Enhanced ASCII
Each function is identified by the extent to which it supports Enhanced
ASCII processing:
Yes = supports Enhanced ASCII.
No = does not support Enhanced ASCII.
Neutral = not sensitive to the issue of ASCII/EBCDIC character encoding.
Socket support appears to be present ("Yes"). Curses functions
aren't mentioned -- they don't even merit a "No". I see nothing
that resembles X.
