RE: 4GL Program Running In Background

When the program is executed in the program, try running it with a variable. Use ARG_VAL(#) to check for variable and set the program to run off the variable. -----Original Message----- From: glynb@bicceri.demon.co.uk [mailto:glynb@bicceri.demon.co.uk] Sent: Wednesday, May 12, 1999 7:14 AM To: informix-list@iiug.org Subject: 4GL Program Running In Background We have a series of 4GL programs that are designed to be able to be run in either foreground or background. When running in foreground, if a database error is encountered, the program opens a window with a message to this effect and reports the error to the program's log. However, if this same program is being run in background (i.e. no terminal is attached) the attempt to display the window (naturally) fails but the program execution fails to terminate. The process then consumes process and engine time until other user's complain about system response and we notice the error in the log file then kill of the executable. Is there any way of a 4GL program detecting that it is being run in background (regardless of whether the parent process is still attached or not). If we were able to detect this we could have the program call an error routine that does not attempt to write back to the terminal.
