VOL vvvvvv[-vvvvvv][,NODSN][,NOCHAIN][,SCRATCH]
                   [,UNEXPIRE][,NOINTAL]

Control Statement Definition

VOL

Is the control statement identifier. It must start in position 1 and be followed by a space.

vvvvvv

Is the volume serial number of the volume to be updated. If two volume serial numbers are indicated (separated by a dash), all volume serial numbers in this inclusive range are selected for update processing. If a range is requested, the NOCHAIN option must be specified. No volumes outside of the specified range are modified.

NODSN

Indicates the data set name does not have to be verified.

NOCHAIN

Indicates the volume to be updated is the second or higher volume sequence of a multivolume data set. Use this with caution because multivolume pointers may be affected. If NOCHAIN is omitted and the VOL control statement is for the first volume of a multivolume data set, updates to any of the listed fields are automatically made for all volumes of that multivolume data set. The fields are:

ACCT	LDATE
BLKSIZE	LJOB
CJOB or J	LPGM
CDATE or C	LRECL
CPGM	LTIME
CSTEP	OUTCODE or O
CTIME	OUTDATE
DEN		RECFM
DSN or D	SMSMC
EXPDT or E	TRTCH
LABEL

If NOCHAIN is specified, the updates are made only to the specified volume.

SCRATCH

Indicates that updates to the TMC Volume record should be made only if the volume is in scratch status.

UNEXPIRE

Indicates that the scratch bit is always turned off following an update. If this operand is omitted, the status of FLAG1 is ignored.

NOINTAL

Indicates that the volume being updated will not have the internal field updated indicator turned on (X'80' in FLAG1).
