I tried the following JCL
~ //STEP1 EXEC PGM=IEFBR14
~ //DD1 DD DSN=NULLFILE,
~ // DISP=(NEW,CATLG),
~ // UNIT=SYSALLDA,SPACE=(CYL,(1,1)),
~ // RECFM=FB,LRECL=80,BLKSIZE=3120
~ //DD2 DD DUMMY,
~ // UNIT=SYSALLDA,SPACE=(CYL,(1,1)),
~ // DISP=(NEW,CATLG),
~ // RECFM=FB,LRECL=80,BLKSIZE=3120
~ //DD3 DD DSN=ADCDMST.NULLFILE,
~ // DISP=(NEW,CATLG),
~ // BLKSIZE=3121,
~ // REFDD=*.DD1
~ //DD4 DD DSN=ADCDMST.DUMMY,
~ // DISP=(NEW,CATLG),
~ // BLKSIZE=3121,
~ // REFDD=*.DD2
The result was two identically defined datasets: LRECL=80, BLKSIZE=3121,
with 1 Cylinder primary and secondary size.
Then I tried
~ //STEP1 EXEC PGM=IEFBR14
~ //DD1 DD DSN=NULLFILE,
~ // DISP=(NEW,CATLG),
~ // UNIT=SYSALLDA,SPACE=(CYL,(1,1)),
~ // RECFM=FB,LRECL=80,BLKSIZE=3120
~ //DD2 DD DUMMY,
~ // UNIT=SYSALLDA,SPACE=(CYL,(1,1)),
~ // DISP=(NEW,CATLG),
~ // RECFM=FB,LRECL=80,BLKSIZE=3120
~ //STEP2 EXEC PGM=IEFBR14
~ //DD3 DD DSN=ADCDMST.NULLFILE,
~ // DISP=(NEW,CATLG),
~ // BLKSIZE=3121,
~ // REFDD=*.STEP1.DD1
~ //DD4 DD DSN=ADCDMST.DUMMY,
~ // DISP=(NEW,CATLG),
~ // BLKSIZE=3121,
~ // REFDD=*.STEP1.DD2
Same result as before. IOW, the DCB information, and the space information
was retained for both DUMMY and DSN=NULLFILE.
What I would like to know is: Where is the difference between DSN=NULLFILE
and DUMMY which Mr. Gilmore asserts (assumes?) ?
