Requesting DLF dump data

To obtain dump data for the DLF class COFGSDO, you need to dump both the DLF address space and its associated data space. Use the DUMP command to dump the data:
 DUMP COMM=(DUMP OF DLF)
 R xx,JOBNAME=DLF,CONT
 R yy,DSPNAME=('DLF'.CCOFGSDO),END

See z/OS MVS System Commands for more information about the DISPLAY and DUMP commands.
