'''Recursion''' in computer science is defined as a function that includes itself as part of its definition but also includes an exit condition. Put simply, '''recursion''' is a function that calls itself, until it doesn't. In [[LabVIEW]] this means a [[VI]] that can calls itself as a [[SubVI]] where the [[SubVI]] call is in a [[Functions Palette/Programming/Structures/Case Structure|Case Structure]] so that a determination can be made whether the [[VI]] needs to call itself again or be done and return. | |||

Recursion in computer science is defined as a function that includes itself as part of its definition but also includes an exit condition. Put simply, recursion is a function that calls itself, until it doesn't. In LabVIEW this means a VI that can calls itself as a SubVI where the SubVI call is in a Case Structure so that a determination can be made whether the VI needs to call itself again or be done and return.
Configuration
To make a VI allowed to call itself as a SubVI it must be set to reentrant. To set a VI to reentrant:
- Open the VI Properties dialog
- Click on the Category->Execution
- Under Reentrancy radio buttons, select the Shared clone reentrant execution
- Then click OK
The VI is now set to reentrant. To use, simply drag the VI Icon to the VI's Block Diagram.
