INTERRUPT causes attention interrupts recognized by the host system to be recognized by Language Environment after the Language Environment environment has been initialized. The way you request that an attention interrupt varies from operating system to operating system. When you request the interrupt, you can give control to your application or to a debug tool.

Non-CICS default

INTERRUPT=((OFF),OVR)

CICS® default

INTERRUPT is ignored under CICS.

Syntax

                       .-OFF-.        .-OVR----.      
>>-INTERRUPT--=--(--(--+-ON--+--)--,--+-NONOVR-+--)------------><

OFF

Specifies that Language Environment does not recognize attention interrupts.

ON

Specifies that Language Environment recognizes attention interrupts. In addition, if you specified the TEST(ERROR) or TEST(ALL) run-time option, the interrupt causes the debug tool to gain control.

OVR

Specifies that the option can be overridden.

NONOVR

Specifies that the option cannot be overridden.

Usage notes

PL/I considerations

Language Environment supports the PL/I method of polling code. The PL/I routine must be compiled with the INTERRUPT compiler option in order for the INTERRUPT runtime option to have an effect.

PL/I MTF considerations

To receive the attention interrupt, the PL/I program must be compiled with the INTERRUPT compiler option, and the INTERRUPT runtime option must be in effect.

The INTERRUPT option applies to the enclave. However, only one thread in the enclave is affected for a particular attention interrupt.
