# data\_only

The data\_only parameter to many [NATS ](https://docs.toomuchmedia.com/additional-resources/common-terms#nats)functions prevents NATS or CARMA from displaying a template. For example, the NATS template function \[\[nats\_list\_linkcodes usually displays [linkcodes ](https://docs.toomuchmedia.com/additional-resources/common-terms#linkcode)using a template and puts them in the {$linkcodes} array, but data\_only lets you change that behavior. For example, the following code will set the {$linkcodes} array without displaying anything to the viewer:

* {nats\_list\_linkcodes data\_only=1}
