## 6.2.7. Dictionary Displays

In AVAP, objects are created and managed using specific commands. An object is created with  `AddvariableToJSON(key, value, object_variable)` , and a key from the object is retrieved with  `variableFromJSON(object_variable, key, var_to_store_key_value)` .

The syntax for dictionary displays is:

```javascript
dict_display       ::=  "{" [dict_item_list | dict_comprehension] "}"
dict_item_list     ::=  dict_item ("," dict_item)* [","]
dict_item          ::=  expression ":" expression | "**" or_expr
dict_comprehension ::=  expression ":" expression comp_for
```

A dictionary display produces a new dictionary object. If a comma-separated sequence of dictionary items is provided, they are evaluated from left to right to define the dictionary entries.
