# create

This block is part of the [`globals`](https://docs.rual.nl/block-types/globals) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

Creates a new function that can be executed using the given name.

- flow `flow`

| `custom function` |
| --- |

Every custom function starts with a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function): public functions are callable from other blueprints, private ones only within their own. The flow runs through the function body, here an [execute](https://docs.rual.nl/block-types/function execution/function_custom_execute) of another function, and ends at [return](https://docs.rual.nl/block-types/function execution/function_return).
