First of all, thank you for your advise. In the meantime I have found out,
that the PROBLEM is more complex. We use the "ssh" for remote login.
This only happens, when you use a terminal emulation (hpterm or xterm)
started with the secure shell (ssh, f.e. ssh badibm13 ;). When I explicitly
use the program "rlogin" (f.e. rlogin fineibm12 :) everything works fine????
But as I explained, when I use ssh and the zsh and I process the cycle
"exec ksh" -> "exec zsh" , then I CAN USE skripts with the zsh in a
remote terminal controled by the ssh?????????? And this is very strange,
don't you think.
Strange too is this behaviour, while invoking a shellskript with
"uglyskript13" does not work (without the ksh-zsh cycle trick), the command
". niceskript10" executes the skript?????? Does the zsh treat the skript
executing mechanisms with and without DOT different? (the skripts are of couse
I do find this behaviour very odd, but with the workaround mentioned
above I can go on using the zsh. Maybe this should be send to the secure
shell people too. Someone should find out, if this only happens with AIX 3.2.
In short: Remote terminal emulation started with the ssh and the zsh, can
not execute a executable skript on AIX 3.2 by typing the name
of the skript. Executing with ". skript" (DOT skript) works.
Rlogin and zsh, or ssh and ksh works too. Executing the ksh
(exec ksh) and then the zsh again (exec zsh), fixes the problem.
