GET Map function

If the GET function has three parameters, the adapter performs the action specified in the -ACTION adapter command on the data in the third parameter of the GET function. In this case, the -FILE adapter command might be omitted. If specified, it will be ignored by the adapter.

If the input data is not provided to the adapter from the execution engine, then the -FILE command must be specified. In that case, the adapter performs the action specified in the -ACTION adapter command on the data from the specified file.

In both cases, the processed data is returned to the execution engine.
