Clobber

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:

0

no clobber: a task will produce an error when trying to overwrite an existing file.

1

clobber: a task will overwrite existing files. This is the default behaviour, in the event that the SAS_CLOBBER variable is undefined.
