KEY
The deletedictionaryvalue statement deletes a key/value pair from a dictionary (see Data Dictionaries).
Parameters
This statement has two parameters:
dictionary – name of the field or variable that contains the dictionary (must contain binary data).
key – is the name of the key/value pair to delete. If this parameter is empty (""), all key/value pairs will be removed.
Description
This statement takes the name (key) of an item and deletes the associated key/value pair from the dictionary. This example deletes the Shipping item from the array.
deletedictionaryvalue myDictionary,"Shipping"
There is a function, deletedictionaryvalue(, that can perform the same operation, and can also delete multiple items in a single operation.
