Specifies whether a new, empty data set can overwrite
an existing SAS data set that has the same name.
| Valid in: |
DATA step and PROC steps

| Category: |
Data Set Control

| Restriction: |
Use with output data sets only.
|
-
YES
-
specifies that a new empty data set with
a given name replaces an existing data set with the same name. This is the
default.
| Interaction: |
When REPEMPTY=YES
and REPLACE=NO, then the data set is not replaced. |
-
NO
-
specifies that a new empty data set with
a given name does not replace an existing data set with the same name.
| Tip: |
Use REPEMPTY=NO to prevent
the following syntax error from replacing the existing data set B with the
new empty data set B that is created by mistake:
data mylib.a set b; |
| Tip: |
For both the convenience
of replacing existing data sets with new ones that contain data and the protection
of not overwriting existing data sets with new empty ones that are created
by accident, set REPLACE=YES and REPEMPTY=NO. |
-
For an individual data set, the REPEMPTY= data
set option overrides the REPEMPTY= option in the LIBNAME statement.
-
The REPEMPTY= and REPLACE= data set options apply
to both permanent and temporary SAS data sets. The REPLACE system option,
however, only applies to permanent SAS data sets.
