UNIX Operating Environment

Identifying the SAS Version Used to Create a File under UNIX

This table identifies the supported file types that are created under the UNIX operating environment by member and SAS version:

UNIX Filename Extensions by Member and SAS Version
Member Type SAS 6 Filename Extension SAS 8 and Later Filename Extension
SAS .sas .sas
PROGRAM (DATA step) .sspnn .sas7bpgm
DATA .ssdnn .sas7bdat
INDEX .snxnn .sas7bndx
CATALOG .sctnn .sas7bcat
MDDB .ssmnn .sas7bmdb
PROC SQL view .snvnn .sas7bvew

In this table, nn is an extension that is used to differentiate among UNIX computer architectures. Here are the extensions and UNIX operating environment groups:

UNIX Operating Environment Filename Extensions
SAS Filename Extension nn UNIX Operating Environment Group Supported by SAS Release
6.09 6.10 6.11 6.12
01 HP-UX Yes Not applicable Yes Yes

Sun Yes Not applicable Yes Yes

Solaris Yes Not applicable Yes Yes

AIX Yes Not applicable Yes Yes

MIPS ABI Not applicable Yes Yes Not applicable
02 ULTRIX Yes Not applicable Not applicable Not applicable
INTEL-ABI Yes Not applicable Yes Yes
04 COMPAQ Digital UNIX Not applicable Yes Yes Yes

SAS 9 and SAS 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.

You can also 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
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.
