Operations
Version 23.4.8839
While Formatters can handle simple data manipulation and formatting, Operations are used for more complex operations in ArcScript.
Operation Basics
Each operation specifies a set of input parameters and output parameters.
You can write scripts, triggered by events, to automate message processing. You can invoke the built-in operations to automate many common tasks when processing, from file I/O to working directly with the protocol used by the connector. The available operations are described below. You can also make calls to the API in the same way that you invoke the built-in operations. Use arc:call to invoke an operation.
