2. In the problem program:

Specify a data control block (DCB) for the data set to receive the
dump. For a standard dump, which has 120 characters per line, the DCB
must specify:

BLKSIZE=882 or 1632
DSORG=PS
LRECL=125
MACRF=(W)
RECFM=VBA

For a high-density dump, which has 204 characters per line and will be
printed on an APA 3800 printer, the DCB must specify:

BLKSIZE=1470 or 2724
DSORG=PS
LRECL=209
MACRF=(W)
RECFM=VBA
