4gl 'error' gives reverse video on entire screen
A user running Informix 4GL 7.32.UC4 on Slackware Linux found that with INFORMIXTERM=terminfo and TERM=xterm, the 4GL ERROR statement (or pressing a function key with no ON KEY handler) left the whole screen stuck in reverse video, needing 'reset' to clear. Ian Goddard suggested xterm's visual bell, but tests (+vb/-vb, and ESC in vi beeping normally) ruled that out; notably no bell sounds under terminfo. Mario Canto blamed incomplete/incorrect termcap/terminfo entries, advising fixing the entry or grabbing one from the IIUG repository. No confirmed fix is recorded.

I'm using Informix 4GL 7.32.UC4 on Slackware Linux 12.1 and any time the 4gl 'error' command is executed the entire screen goes reverse video. It only does this if I set INFORMIXTERM=terminfo. I need this because function keys don't work unless I use terminfo. It also does the reverse video on the entire screen if I press a function key which does not have an 'on key' associated with it. Any ideas what is causing this display problem? I'm using TERM=xterm.

I'm using TERM=xterm. Do you mean it just goes reverse for a moment and then back to normal? If so that sounds like xterm's visual bell. Application sends the BEL char. xterm doesn't know how to go "ding" so it flashes the screen instead. -- Ian Hotmail is for spammers. Real mail address is igoddard at nildram co uk

What you suggest does sound like a possibility, I'll investigate how to turn off the bell and see if that's it. It does this anytime an invalid key is pressed so I think you may be on to something.

You can define the function keys in termcap, or fix the wrong terminfo entry to go back from reverse screen. Or you can download one of many termcap/terminfo files in the iiug repository.

If the same thing happens, even if it's supposed to be off then (a) it is a visual bell and (b) xterm's mishandling it. You could also try some other terminal emulator such as gnome-terminal. -- Ian Hotmail is for spammers. Real mail address is igoddard at nildram co uk

Real mail address is igoddard > at nildram co uk It works in vi. If I hit ESC while not in insert mode, it beeps. If I start the xterm with -vb then the screen flashes in reverse, but does go back to normal. So it seems the 4gl problem of staying in reverse is a different issue.

Real mail address is igoddard > at nildram co uk The xterm bell does not sound when using terminfo with 4gl, but anytime it should sound is when I get the entire screen in reverse.
