It's been answered, but it's worth noting that it's "ECB", not "ECB(s)". That is, there is effectively but one such ECB per address space, so multiple tasks cannot have their own independent notifications from stop or modify commands. There is neither syntax nor infrastructure provided to direct a stop or modify to a unit of work within an address space.UNIX on z/OS does provide the ability to direct signals to processes, and perhaps even to threads, iirc. In passing, there is another really annoying limitation imposed on programs that use the IBM callable service BPX1CCS (aka __console() or __console2() ), which are the only console services available to C programmers unless you write your own assembler interface. These services arrogate to themselves use of the entire name space on the modify command that rightly belongs to the application program, and dole out to the application only the limited subset that follows the string "APPL=". But I've ranted about this before...
