HI and friends are "conditions" in the REXX interpreter, that are checked at each instruction (REXX clause, I assume that means). It's just a matter of turning the flag on using the IRXIC service, and the interpreter will notice it some time real soon. Unless, of course, there is a long-running single clause such as a call to some external environment.
