*ALLOCATE
The format of the ALLOCATE command is:
.ALLOCATE resource: logical-name: /switches
Resource represents the name of the resource to be ALLOCATEd
and must be one of the following:
A disk volume set name such as DSKB:
A tape volume set definition such as PAY-WK43(PM43A,PM43B):
A logical-name previously associated with a resource
Note: Physical/generic device names are illegal volume set names
for the ALLOCATE command.
Logical-name represents the name your program will use to
reference the resource. If this field is not specified and
the resource was a tape volume set, a default will
be generated by abbreviating the volume set name to 6 characters
or up to the first non-alphanumeric.
For example, PAY-WK43 would produce a default logical name
of PAY.
/NOTIFY implies that you wish to receive notification upon completion
of the request and when tape volumes are switched.
/CHECK
Will print the status of allocation requests for your job.
/HELP
Will print a description of the ALLOCATE command.
/TAPE
Indicates that the resource is a tape volume set.
/DISK
Indicates that the resource is a disk volume set.
/EXCLUSIVE
Ensures that no other users are allowed to share the resource. This
is the default for tape volume sets.
/SHARABLE
Allows other users to share the resource. This switch is not valid for
tape requests and is the default for disk requests.
/READ-ONLY
Ensures that the resource is write-locked when it is ALLOCATEd.
This is the default for tape volume sets.
/WRITE-ENABLE
Ensures that the resource is write-enabled when it is ALLOCATEd. This
is the default for disk volume sets.
/REMARK:"text"
Allows a remark up to 50 characters in length to be sent to the
operator with this ALLOCATE request. This switch is required
for tape ALLOCATE requests if no volume identifiers were specified
in the request.
/ACTIVE
Ensures that the disk volume set is placed in your job's active
search list. This is the default for disk ALLOCATE requests.
/PASSIVE
Requests that the disk volume set be places in your job's passive
search list.
/CREATE
Allows creation of files on a disk volume set.
This is the default for disk ALLOCATE requests.
/NOCREATE
Prohibits creation of files on a disk volume set unless the structure
is explicitly requested by name.
/TRACKS: 7 ! 9
Specifies the number of tracks for a tape volume set.
/DENSITY: 200-BPI ! 556-BPI ! 800-BPI ! 1600-BPI ! 6250-BPI
Specifies the density of the tape volume set.
/LABEL-TYPE: ANSI ! EBCDIC ! USER-EOT ! NONE ! NOLABELS ! BYPASS ! IBM
Specifies the type of label required for the tape volume set.
ANSI Specifies the tape volume set has ANSI standard labels.
IBM Specifies the tape volume set has EBCDIC (HEX) labels.
EBCDIC Same as IBM.
USER-EOT Specifies that the tape volume set is not labeled and
the user wants to see EOT (end-of-tape).
Volume switches will not be processed automatically
by MDA and must be processed by the user program.
This label type should be used for programs like
BACKUP that have their own user labels.
BLP Same as BYPASS.
BYPASS Specifies that MDA is not to perform any label processing.
The user must be privileged to request this label type.
NONE Same as NOLABELS.
NOLABELS Specifies that the tape volume set is not labeled and user
will never see EOT (end-of-tape). Volume switches will
be processed automatically by MDA.
UNLABELED Same as NOLABELS.
/VOLID:(list) Specifies the tape volume identifiers of the volumes in
the tape volume set. Use this switch only if the
the identifiers were not previously specified.
/SCRATCH Requests the operator to allocate tapes for
this request from a pool of scratch tapes for
temporary use.
/NEW-VOLUME-SET Requests the operator to allocate tapes for this
request from a pool of new volumes.
