VTOC Statement Syntax
Apply the following rules to the VTOC statement:
• The VTOC control statement uses a free-form keyword format.
• Start the VTOC command in position one, followed by at least one space.
• Separate all operands with commas.
• Positions 72—80 of each input command are ignored.
• Continuation statements are not supported.
• Do not include any comments in the statement.
This command has the following format:
VTOC STRTADR= {nnnnnn|cccchh }, EXTENTS=nnnnn[, CISIZE=nnnnn ]
[, SYSNO=nnn ]
[, OLDVOLID=xxxxxx ]
VTOC
Controls the characteristics of the new VTOC.
STRTADR= {nnnnnn|cccchh }
Defines the beginning address of the VTOC extent, PBN if FBA, or CCCCHH if
CKD. It can overlap the old extent.
EXTENTS=nnnnn
CISIZE=nnnnn
OLDVOLID=xxxxxx
SYSNO=nnn
Indicates the number of Format 4 and Format 5 records for FBA; number of
tracks desired in new VTOC for CKD.
Optional operand. Specifies the CISIZE in bytes desired for the new VTOC for
FBA. The recommended size is 2048. This operand is ignored for CKD. The
default is 1024.
Optional operand. Identifies the volume serial number of the DASD volume to
be reformatted. If omitted, the default is whatever volser is found on the
assigned volume.
Optional operand. Defines the logical unit to be used to read the old VTOC and
write a new one. The logical unit must be assigned to the proper device. If not
specified, SYS001 is the default.
