>>-HI----------------------------------------------------------><

HI (Halt Interpretation) is an immediate command you can use to halt the interpretation of all currently executing execs. The HI immediate command is available only if an exec is running in TSO/E and you press the attention interrupt key to enter attention mode. You can enter HI in response to the REXX attention prompting message, IRX0920I.

After you enter HI, exec processing ends or control passes to a routine or label if the halt condition trap has been turned on in the exec. For example, if the exec contains a SIGNAL ON HALT instruction and exec processing is interrupted by HI, control passes to the HALT: label in the exec. See Conditions and condition traps for information about the halt condition.

Example

You are running an exec in TSO/E that is in an infinite loop. To halt interpretation of the exec, press the attention interrupt key. The system issues the REXX attention prompting message that asks you to enter either a null line to continue or an immediate command. Enter HI to halt interpretation.
