This table identifies the supported file types that are created under the UNIX operating environment by member and SAS version:
Member Type | SAS 6 Filename Extension | SAS 8 and Later Filename Extension |
---|---|---|
SAS | .sas | .sas |
PROGRAM (DATA step) | .ssp nn | .sas7bpgm |
DATA | .ssd nn | .sas7bdat |
INDEX | .snx nn | .sas7bndx |
CATALOG | .sct nn | .sas7bcat |
MDDB | .ssm nn | .sas7bmdb |
PROC SQL view | .snv nn | .sas7bvew |
where: nn is an extension that is used to differentiate among UNIX machine architectures. Here are the extensions and UNIX operating environment groups:
SAS Filename Extension nn | UNIX Operating Environment Group | Supported by SAS | |||
---|---|---|---|---|---|
6.09 | 6.10 | 6.11 | 6.12 | ||
01 | HP-UX | ¢ | n/a | ¢ | ¢ |
Sun | ¢ | n/a | ¢ | ¢ | |
Solaris | ¢ | n/a | ¢ | ¢ | |
AIX | ¢ | n/a | ¢ | ¢ | |
MIPS ABI | n/a | ¢ | ¢ | n/a | |
02 | ULTRIX | ¢ | n/a | n/a | n/a |
INTEL-ABI | ¢ | n/a | ¢ | ¢ | |
04 | COMPAQ Digital UNIX | n/a | ¢ | ¢ | ¢ |
SAS 9 and 8 filename extensions are identical.
Because data sets are interchangeable among HP-UX, Sun, Solaris, AIX, and MIPS operating environments, the creation of a transport file for moving among them is not necessary. Catalogs are also interchangeable among AIX, HP-UX, Sun, Solaris, and MIPS operating environments.
Furthermore, you can use the CONTENTS procedure to display information about the data.
Here is an excerpt of typical PROC CONTENTS output, which identifies the member and the engine that was used to create it:
The SAS System The CONTENTS Procedure Data Set Name: TEST.RECORDS Member Type: DATA Engine: V9
The output shows that the data set TEST.RECORDS is a member of type DATA, and that it was created with the V9 engine.
