Indicates whether this dataset is writeable (Dataset class)
This Boolean property indicates
whether or not the dataset is an output dataset,
that is, whether it is to be written to or not.
It is only settable while the object is in the Closed state.
An attempt to set it while the dataset is not closed results in request
cancellation.
Syntax
%currentBoolean = dataset:Output dataset:Output = newBoolean
Syntax terms

|---|---|
| dataset | A reference to an instance of a Dataset object. |

- Output is a boolean value, that is, it must be True or False.
- The initial value for Output is False. That is, by default, datasets are input datasets.
