First, my translation how I understand your question, then my suggestion: * You don't want to exit the program if the user enters "ctrl-c" !?! -> Map the interrupt key to another key, like ctrl-# ( visible ^^ ) Enter at the command line: $ stty intr "^^" $ startyourapplication You want an interrupt to be send to your program if the user hits the function key F7 !?! * Read your terminal description whether it's possible to program your function keys. -> Define the characters to be send to the computer as "ctrl-#". Your stty-driver will map this key to the interruot key, now. * You want the function key F9 to work as accept key !?! -> OPTIONS ACCEPT KEY F9 If your 4GL application will not understand the F9 key, you must define this key in your termcap entry. ( I think Informix does not support the terminfo on HP-UX ). Therfore the termcap should be used. If you have no idea of what your terminal sends to your computer when you press the F9 key, you can find it out very easy: $ od -c press the F9 key several times, then enter a newline and <ctrl-d> The od-command will display the bytes sent to your box. The output is shown either in visible characters, or in octal representation. ( 033 means Escape, in your termcap entry you will find the \\E character. If the display looks like: 033 [ 2 0 ~ 033 [ 2 0 this stands for the termcap value \\033[20~ The appropriate entry would look like this: :k8=\\E[20~: I know that the original termcap makes a difference between the number of function keys defined in the entry. If you have more than 10 function keys F1 to F20, then the first function key would start either at "k0" or "k1". But I can't remember in which case it should start with "k0" and when it would start with "k1". I think you will find it out when you defined "k2". Far as I know, there is a command to convert a terminfo entry to an old termcap entry. On HP-UX I think there is no "captoinfo" command. On HP-UX 10.20 I guess there is the "infocmp" command available and the conversion option should be -C, infocmp -C will generate the termcap entry that should work for your terminal. Possibly it contains the function keys as well. * Finally, how can you define an exit key !?! -> I think this should be done by the programmer. INPUT ..... AFTER INPUT LET status = TRUE ON KEY( F11 ) LET status = FALSE EXIT INPUT END INPUT ... LET status = TRUE PROMPT "Enter a number" FOR number_i ON KEY( F11 ) LET status = FALSE END PROMPT ...
