>An LA instruction can not program check. It can not produce an interrupt when it is executed, but it can appear to have done so. I produced a S0C4 by trying to execute an LA instruction in storage whose storage key did not match that of the current PSW, and neither of the two keys was zero. The S0C4 was generated in fetching the LA rather than executing it. When I studied the dump, it first appeared that the LA itself had caused the interrupt, since the PSW pointed to the LA, when in fact the LA could have been any operation code and there still would have been a S0C4.
