Informix Terminal Control Keys description

Posted in 2010

Summary

A user wanted a list of the control/special keys Informix uses and their meanings, having failed to make sense of /usr/informix/etc/termcap. After clarifying he meant I4GL, he was pointed at the 4GL manual, and Art Kagel listed the trappable special keys (ACCEPT, INTERRUPT, ENTER, INSERT, DELETE, PRINT, arrows, PAGE_UP/DOWN, F1-F12 and shifted variants, plus other control keys), noting function keys must be mapped in termcap/terminfo. For CTRL-R he explained it is the curses refresh key (KEY_REFRESH, termcap code &2, see man 5 termcap). The poster then found the description in the I4GL 7.32 Reference Manual (p. 492), so the question was resolved.

Hi all, It may be a silly question but.... I would like to have a list of all the Control keys used in Informix and their function descriptions. I have looked at /usr/informix/etc/Termcap but still cannot interprete its contents. Regards, Long N

I assume from your previous posting that you are asking about which 'special' keys Informix 4GL applications can use to provide users with control keys. Here's what I know: 4GL's Internally "special" keys (these are assignable to any function key or control key you want: <ACCEPT> - Used by INPUT statements to accept the currently entered record - defaults to <ENTER> <INTerrupt> - Used by INPUT and other forms statements to stop processing - defaults to the user's stty int key setting Special, control, and function keys: <ENTER> <INSERT> <DELETE> <PRINT>: On a 'real' VT100 terminal this is F5 and many TERMCAP files still map it that way, so F5 may not be trappable for that TERM setting unless you modify the TERMCAP entry <UP> <DOWN> <LEFT> <RIGHT> <PAGE_UP> <PAGE_DOWN> <F1> through <F12>: Must be mapped properly in the TERMCAP or TERMINFO file <SHIFT_F1> through <SHIFT_F12>: Must be mapped properly in the TERMCAP or TERMINFO file All defined control keys not mapped to a special key (so the user's stty int key is not trappable as a control key> Art Art S.

Hi Art, Thanks for the input. Where can I find the definition of CTRL-R (redisplay screen?). Is it in Termcap?

IB control-R is a Curses built-in. Yes, it is called the refresh key and is represented in curses by the constant KEY_REFRESH. In the TERMCAP file it is mapped by the code &2 (see "man 5 termcap" on most UNIX and Linux systems - if you don't have the man pages, install the pdcurses package it will install the man pages).
