The delete (normally ^?) key maps to some silly <esc>[P code. This is not specific to AIX 3.1. I have seen it on the AIXterm of AIX 370 and AIX 2.2.1 too. On AIX 3.1 it happens on the HFT and the AIXterm. It is probably a simple X type keymap problem, but has been MOST irritating. In fact, this is my most frequent complaint around the office when I am mad at the silly OS: "F***ing IBM can't even get the delete key right..." ;-) Also there is some problem with the yp groups. You have to keep a local version of the /etc/group file, and the group names have to be short. Otherwise you can't log in. And no diagnostic. (If your group is listed in the NIS/YP map but not on the local machine, forget it.) A five minute user creation took 3 hours because of this one. And now a query, Anyone succesfully ported X11R4? Diffs available? Thanks in Advance! Ej P.S. I have found a bug in the -lm library. the pow function will dump core at times. This is easily fixed by writing the function yourself. (probably at a loss of speed) P.P.S. It is still a very fast machine. All the programs I can manage to get compiled run like lightning. At a demo we were running localy using RPC to do a mandelbrot set, we ran 3 instances on the rs6000 while the rest of the net (SS, Decstations, sony's) were only running 1. The rs6000 was still faster. If the OS was nicer this would be a class machine.

I set the environment variable XENVIRONMENT to the value $HOME/.Xresources.aix so only programs running on the AIX machine get these resources. The resources set the xterm terminal modes to use Delete instead of Backspace, and (within xterm only) remaps the keysym ``Delete'' to insert what you normally expece the Delete key to insert -- ASCII code 127 (decimal). The second file, .Xmodmap.aix, makes the BackSpace and Delete keys equivalent. It also swaps the Control and Caps Lock keys, so I end up with a keyboard that doesn't make me want to break it into little pieces after 5 minutes' use. I put the following line in my .xinitrc to make the keymap change: xmodmap .Xresources.aix Those who think BackSpace is the right way to delete backwards, and the Control key is less important than Caps Lock, will probably not find these changes of much use. If you're using an RS/6000 in a Sun or DEC environment, though, they may help. ----------------------------- .Xresources.aix -------------------------------- ! !

This is in a OS/CPU-specific resource file because R4 xterms complain ! if I use XTerm*Translations to set the translations (because only the !
