This chapter describes the CICS BAC file maintenance utility that you can use as an alternative to the workstation administration client or the ISPF administration interface, which are discussed in CICS BAC workstation administration client (see also the CICS Batch Application Control for z/OS Workstation User's Guide) and CICS BAC ISPF administration interface. You can run the CICS BAC file maintenance utility as a batch job to create and maintain information in a CICS BAC VSAM KSDS control file.
