Like Mike said, run your own CCW's with EXCP or similar. But you could also get a quick look with a program that already does this, such as: //ADRDSSU EXEC PGM=ADRDSSU //SYSPRINT DD SYSOUT=* //VOL DD UNIT=3390,VOL=SER=VOLSER,DISP=OLD //SYSIN DD * PRINT INDD(VOL) TRACKS(0,1,5,15)

I remember adding X'00' to the instruction stream of a JES2 exit so it would abend on a test box, in order to dump data at that point. I was very confused because it got an 0C4 instead. Turned out the previous owner apparently never tested the recovery routine. But I think it's overkill for
