%Q

In interactive processing, the %Q command is ignored. When issued in batch mode, the %Q command causes the output of maps, or screens produced by INPUT statements, to be suppressed.

SET CONTROL 'Q' causes the next INPUT statement not to be processed. This may be used, for example, if at the end of a helproutine the processing is to continue without the user having to press ENTER upon return from the help to the map.
