Eloquence does not work in background

This probably related to the WAIT statement which behaves differently in background (stdin not connected to a tty device). This is used to provide batch input to Eloquence programs ("PERFORM files").

In background, a WAIT statement which specifies a delay is simply ignored and an unconditional WAIT results in reading the next line from stdin. When an EOF is encountered, the program is terminated.

If this is not the desired behaviour (eg. the program is crontroling data capture devices) you can replace the WAIT statement by the SLEEP statement. The SLEEP statement behaves the same in background and foreground mode.

Please refer to Eloquence reference manual for more information.
