To update the UADS and the broadcast data set from a terminal, ensure that the UADS to be updated is allocated by the SYSUADS DD statement, either in a LOGON procedure or by using the ALLOCATE command. Make the updates (additions, changes, and deletions) using the ACCOUNT command and its subcommands.

To update the UADS and the broadcast data set with a batch job, you can use the sample JCL shown in Figure 1. For an explanation of this JCL, see Executing the terminal monitor program. If you do not include a DD statement specifying the broadcast data set, the data set must be cataloged.

//jobname     JOB     job card parameters
//            EXEC    PGM=IKJEFT01
//SYSTSPRT    DD      SYSOUT=A
//SYSUADS     DD      DSN=SYS1.UADS,DISP=SHR
//SYSLBC      DD      DSN=broadcast-data-set,DISP=SHR,VOL=SER=volser,UNIT=device
//SYSTSIN     DD      *
