Join String

Use Join String with the ordered inputs below.

Where to find it

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

Inputs

Input	Type	Role	Requirement	Default / constraint
Destination	String	Variable binding	Required	Required
Strings	List	Variable binding	Required	Required
Separator	String	Value	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: Join String
Destination: Private String result
Strings: Private List<T> value1
Separator: example

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

Indices exposed by these operations are 1-based. String output, regex work, and execution budgets remain bounded. Select the tags above for case/regex/matching modes where provided.

Runtime validation: Join String requires List.
