# Variables & Data storage

> Action blocks for variables & data storage in the Meridian builder.

Persist data across runs (Storage) or within a single execution (temporary variables).

Categories mirror the builder block palette. Search the palette or use the links below to jump to a specific block.

* [Create a Variable](/builder/action-blocks/variables-and-data-storage/create-var) — Create persistent Storage data that survives between runs.
* [Create a Temporary Variable](/builder/action-blocks/variables-and-data-storage/create-temp-var) — Store data for the current execution only.
* [Delete a Temporary Variable](/builder/action-blocks/variables-and-data-storage/delete-temp-var) — Remove a temporary variable from the current run.
* [Calculate](/builder/action-blocks/variables-and-data-storage/calculate) — Perform math operations and save the result to a variable.
