Jonathan Scott -----Original Message----- From: IBM Mainframe Assembler List <[email protected]> On Behalf Of Philippe Leite Sent: 10 December 2025 15:10 To: [email protected] Subject: SVC Screening Hi guys, I want to use the SVC screening process to intercept three SVCs. During the execution of the subsystem routine, how can I know which of the SVCs has been intercepted? Is this possible? Is there a control block where I can obtain this information? Thank you in advance. Philippe Leite
