z/OS UNIX provides a CBSTAT exit routine to provide control block status information. The CBSTAT exit routine displays control block status information at the ASCB or TCB level. The CBSTAT exit routine is invoked when a user enters the IPCS CBSTAT subcommand with a keyword of STRUCTURE(ASCB) or STRUCTURE(TCB). If the ASCB or TCB belongs to a z/OS UNIX user, then control block status will be given for the address space or task, respectively. Refer to z/OS MVS IPCS Commands and z/OS MVS IPCS User's Guide for information on the CBSTAT subcommand.
