Required Arguments
Optional Arguments
- ALTER=alter-password
-
provides the Alter password for any alter-protected SAS files named in the AGE statement. Because an AGE statement renames and deletes SAS files, you need Alter access to use the AGE statement. You can use the option either in parentheses after the name of each SAS file or after a forward slash.
- MEMTYPE=mtype
-
restricts processing to one member type. All of the SAS files that you name in the AGE statement must be the same member type. You can use the option either in parentheses after the name of each SAS file or after a forward slash.Alias:MTYPE=, MT=Default:If you do not specify MEMTYPE= in the PROC DATASETS statement, the default is DATA.
Details
The AGE statement renames
the current-name to the name of the first
name in the related-SAS-files, renames
the first name in the related-SAS-files to
the second name in the related-SAS-files,
and so on, until it changes the name of the next-to-last SAS file
in the related-SAS-files to the last name
in the related-SAS-files. The AGE statement
then deletes the last file in the related-SAS-files.
If the first SAS file
named in the AGE statement does not exist in the SAS library, PROC
DATASETS stops processing the RUN group containing the AGE statement
and issues an error message. The AGE statement does not age any of
the related-SAS-files. To override this
behavior, use the NOWARN option in the PROC DATASETS statement.
If one of the related-SAS-files does
not exist, the procedure prints a warning message to the SAS log but
continues to age the SAS files that it can.
You can age only entire
generation groups. For example, if data sets A and B have generation
groups, then the following statement deletes generation group B and
ages (renames) generation group A to the name B:
age a b;For example, suppose the generation group for data set A has three historical versions and the generation group for data set B has two historical versions. Then aging A to B has this effect:
