>Just told me that debug tool can use SVC 97 as a interrupt TSO TEST, HLASM IDF and developer debugger all can use SVC97. If it's use is not documented in the specific product documentation, then it's not a user interface. However, the SVC is documented at https://www.ibm.com/docs/en/zos/3.2.0?topic=descriptions-svc-97-0a61. SVC97 provides a lot of functionality but the line "Used by any module of the tested program; as a breakpoint handler, the TCBTCP bit is X'1' in the current TCB. R15, R0, and R1 - No applicable data." seems it's a possibility but https://www.ibm.com/docs/en/developer-for-zos/17.0.x?topic=applications-debugging-subtasks-created-by-attach-assembler-macro implies there will be situations where this might not work. Use at your own risk unless you can find specific documentation in developer debugger. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
