Interrupting a SAS Session

Under CMS, if you run SAS in either the windowing environment or interactive line mode, you can interrupt SAS processing. The method that you use depends on what type of terminal you use and on certain CP terminal options.

Interrupting a Windowing Environment Session

You can use the BREAK key (PA1) to interrupt your SAS session. (On an SNA terminal, you can also use the ATTN key.) Usually, you must first press the RESET key to unlock the keyboard before pressing the PA1 key.

The first time you press PA1, your terminal is merely placed in CP READ status. Press PA1 again to activate BREAK key processing, or enter a BEGIN command to return to your SAS session instead. When SAS processing is interrupted, a requestor window asks you to specify an action. In most cases, you can choose either to continue or to terminate the current process.

Interrupting an Interactive Line Mode Session

To interrupt an interactive line mode session, use the BREAK command. BREAK is a CMS immediate command--that is, it is processed as soon as it is entered.
