The WFLUSH-INHIBIT op-code starts the bufferization of INQUIRE statements to reduce client/server traffic. Normally every INQUIRE causes client/server traffic. By bufferizing them, and send more of them at once, you can reduce the traffic.

Bufferized INQUIRE statements are sent when WFLUSH-ALLOW is called or when one of the other conditions listed in UI changes bufferization occurs. The destination variables of your inquires should be checked only after that moment.

It's important to use a separate variable for each INQUIRE (e.g. use occurs data items). If you use the same variable for multiple inquires, such variable will be set to the result of the last INQUIRE overwriting values set by previous inquires.
