Set Dictionary Value

Adds or replaces the value at Key. Keys/values must match the dictionary’s invariant declarations.

Where to find it

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

Inputs

Input	Type	Role	Requirement	Default / constraint
Dictionary	Dictionary<K,V>	Variable binding	Required	Required
Key	Compatible declared type	Value	Required	Required
Value	Compatible declared type	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: Set Dictionary Value
Dictionary: Private Dictionary<K,V> result
Key: Number 1 (match the destination/element type)
Value: Number 1 (match the destination/element type)

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.

Runtime validation: Dictionary sorting requires non-null Number or String keys/values.
