You can use the CONTENTS procedure on all operating environments that use SAS 6 and later to find which Base SAS engine was used to create a SAS file.
Note | Because z/OS operating environments do not use filename extensions, you must use PROC CONTENTS to identify the SAS base engine that was used to create SAS files under these operating environments. |
Here is an example of using PROC CONTENTS on a data set in the z/OS environment:
proc contents data=test.records; run;
Here is an excerpt of the output:
The SAS System The CONTENTS Procedure Data Set Name: TEST.RECORDS Member Type: DATA Engine: V9
The output shows that the data set RECORDS is a member of type DATA, and that it was created with the V9 engine.
You can also use PROC CONTENTS to find out whether a data set's operating environment format is foreign or native to the accessing operating environment. For more information, see "Identifying the Format of a SAS File" on page 15.
