I'm also confused by your question. What makes you ask this question? What did you read or hear about that made you ask this question? Are you talking about the "subsystem interface" or is SSI in reference to something else?
Any time a program moves information to storage, it is overlaying storage. It's only a bad thing when it overlays the wrong storage. We use the term "storage overlay" to mean overlaying the wrong storage. Assembler macro IEFSSI and MVS command SETSSI add/update the SSCT which overlays information in an SSCT or the SSCT chain. If your program overlays the wrong storage, then it can cause abends. Great care must be taken in programs that run from the SSI. The SSI runs all the time and in all address spaces. If something bad happens, you could be IPL'ing your system.
