By default when the dal is used to create a new dataset, an existing dataset
with the same name will be overwritten. This is referred to as clobbering.
If the environment variable SAS_CLOBBER is defined, to determines the clobber behaviour. It can take the following values:
- no clobber: a task will produce an error when trying to overwrite an
- clobber: a task will overwrite existing files. This is the default behaviour, in the event that the SAS_CLOBBER variable is undefined.
