Get List Length

Use Get List Length with the ordered inputs below.

Where to find it

Set Variable → Operations → Choose Operation → List. Requires Dev access to configure, then a successful compile to activate.

Inputs

Input	Type	Role	Requirement	Default / constraint
Destination	Number	Variable binding	Required	Required
List	List	Variable binding	Required	Required

Result and behavior

Stores the result in the first configured destination Variable. Its type must match the result and any generic element/key types.

Configuration example

Block: Set Variable → Operations
Operation: Get List Length
Destination: Private Number result
List: Private List<T> value1

Use this as an editor configuration: declare any Variables/collections first and choose real locations/eligible targets for your plot. It is not pasteable source code.

Restrictions and troubleshooting

Initialize the collection first. Element/key/value declarations are invariant. Reference inputs share mutable contents; choose a copy mode when isolation is required. List indices begin at 1; unsuccessful index searches return 0.
