DIP
The dataset is initialized with a LOGREC header record.
CVOL
The dataset is initialized as an OS SYSCTLG containing the minimum entries
needed to IPL an OS/360 system.
VTOC filename
Specifies the size and location of the VTOC. A dataset name must be coded on this
statement although it is not used. If no VTOC statement is present, the VTOC will
be placed after the last dataset on the volume and the size of the VTOC will be the
minimum number of tracks necessary.
units
This specifies the space allocation units: ‘TRK’ or ‘CYL’.
pri
This is the space allocation primary quantity.
sec
This is the space allocation secondary quantity.
dir
This is the number of directory blocks.
dsorg
This specifies the dataset organization: ‘PS’, ‘PO’, ‘DA’ or ‘IS’.
recfm
This is the record format: ‘F’, ‘FB’, ‘FBS’, ‘V’, ‘VB’, ‘VBS’ or ‘U’.
lrecl
This is the logical record length.
blksize
This is the block size.
keylen
This is the key length.
All parameters except the dsname and method are optional. Defaults of zero are supplied for DCB para-
meters. For datasets loaded with the XMIT method the DCB parameters are taken from the unloaded
PDS, minimum space allocation required to load the dataset is used unless a larger quantity is specified.
If space allocation is omitted the default is ‘TRK 1 0 0’. If CYL is specified without any primary quantity
then the default allocation is 1 cylinder or the minimum number of cylinders required to load the dataset,
whichever is larger.
5.11.5 Examples
Example 1:
Create a 2314 volume in a file called SYSRES.230 using the control file SYSRES.PLF with message
level 2.
DASDLOAD SYSRES.PLF SYSRES230 2
The corresponding control file SYSRES.PLF looks like the following:
# Pack layout file for MFT system residence volume
sysres 2314 * ieaipl00.rdr
sys1.parmlib xmit /cdrom/os360/reslibs/parmlib.xmi
