# Stream Set Temporary Variable Action With the help of the Stream Set Temporary Variable Action it is possible to set a variable in the stream and to query it at any point in the stream using the wildcard {stream.variable.?}. For example, a path that occurs repeatedly within the stream would be easier to retrieve. The variable is no longer available after the stream has ended, but it is available in a directly following stream, for example if it was set in a prestream. It will be set again the next time the same stream is executed. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.helmut.de/helmut4-releases/v4.6.0/helmut4-components/streamdesigner/nodes/actions/misc/stream-set-temporary-variable-action.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
