We routinely run the following JCL:
//STATS1 EXEC PGM=AFOLIBR,PARM='NRJS,NJTA' //SYSPRINT DD SYSOUT=* //MASTER DD DSN=NCPS.LIBRCM.SRCLIB,DISP=SHR //OSJOB DD DUMMY,DCB=(RECFM=F,LRECL=80,BLKSIZE=80) //INDEX DD SYSOUT=* //SYSIN DD * -OPT NOSEP,INDEX(S) -END /* After converting all of our datasets to SMS datasets we occasionally get a few dead blocks (DUE TO PROGRAM ABENDS) when we run the same JCL. Is this anything to be concerned about since everything seems to function Ok?
