dal (dal-1.193) [xmmsas_20190531_1155-18.0.0]
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.
