SAS Companion for the OS/390 Environment

Connecting to SAS under OS/390

Under OS/390, you can access or connect to a SAS session in any of the following ways:

3270 terminals: You can use devices that support extended data streams as well as those that do not. See Terminal Support in the OS/390 Environment for more information about terminal support.
terminal emulators: Terminal emulators that you can use to access SAS on OS/390 include Emulus (available from SAS Institute),(footnote 1) Attachmate Extra!, Hummingbird Host Explorer, and others.
SAS/CONNECT software: SAS/CONNECT supports cooperative and distributed processing between OS/390 and Windows, OS/2, UNIX, OpenVMS, and CMS. It supports several advanced communications protocols (including TCP/IP, APPC, TELNET, EHLLAPI, ASYNC, and 3270), enabling local clients who are running SAS to communicate with one or more SAS applications or programs that are running in remote environments. For more information, see SAS/CONNECT User's Guide.
SAS/SHARE software: SAS/SHARE enables local and remote clients in a heterogeneous network to update SAS data concurrently. It also provides a low-overhead method for multiple remote clients to read local SAS data. For more information, see SAS/SHARE User's Guide.
SAS/SESSION: SAS/SESSION enables terminal users who are connected to the Customer Information Control System (CICS) to communicate with the SAS System in an OS/390 environment. It uses the LU6.2 (APPC/MVS) protocol. Your local SAS Support Consultant will find more information about SAS/SESSION in the installation instructions for the SAS System in the OS/390 environment.

FOOTNOTE 1: Although Emulus software is available from SAS Institute, it operates independently of the SAS System and its applications. It offers enhancements to 3270 terminal operations as well as extended, interactive features for users of SAS graphics applications.
