If the value zero is entered in the parameter CURRENT UPDATE BURST REC.:, editran/P assumes that it is a Matrix buffer with SHR (2,3), so it will not perform ENQ/DEQ on it, allowing several tasks to run concurrently on the file. In the presentation profile, the volume in which you want to catalog and the number of records in the primary space of the buffer are specified (a secondary space of 25% of the primary is assigned).

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## 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, and the optional `goal` query parameter: ``` GET https://docs.editran.onesait.com/documentacion-editran/ibm-editran-v5.3-cics-en/definition-and-management-of-buffer-files/definition-in-editran-profiles.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
