I've successfully compiled a hacked-up ksh on a PS/2 model 80, running AIX. It seems to work fine, except that users (even ones with system as their primary group) can't su with it, and can't use the open command - it returns error 069-055: 'You cannot Open the "xxx" window because the system cannot find the necessary control information', which the messages reference says is caused because the system was not able to Open the console window. What's the problem? Do I have to hack on the ksh more? I notice that open and on are documented in the sh and csh man pages, indicating that they may be shell builtins. Oh - by hacked-up, I mean a ksh that behaves in a little more "tenex"-like fashion: completion on tab or esc, listing on '?', more emacs-like control-t behavior, uppercase et. al. backwards added, and a "kept forks" concept, similar to tops-20's kept jobs. These shouldn't be causing my problems, though. Ben -- Benjamin Fried ben@cunixf.cc.columbia.edu rutgers!columbia!ben

AIX PS/2's setpgrp() is the Sys V setpgrp. You want to call instead
setpgid(pid, pgrp), which has the same calling sequence as BSD4.3's setpgrp.
If you DON'T do this, and mistakenly call setpgrp(), you'll get the problems
you report ("open" command not working, etc.)
