CA Dynam for VSE User Guide

DYNCAT Commands
TAPEopt=
Optional parameter. Changes the default processing options performed during
open and close by CA Dynam/T. Enclose options in parentheses, separated
with commas or blanks. Valid options are:
RELEASE or NORELSE
Indicates whether this WORK dataset will be scratched at
CLOSE. This parameter is only valid for datasets specified
as WORK=YES.
HOLD or NOHOLD Determines whether the CA Dynam/T HOLD option (to
hold assignment) will be in effect at CLOSE.
DROP or NODROP Specifies whether the CA Dynam/T DROP option (to erase
TLBL at file CLOSE) will be in effect.
MODIFY or NOMODIFY
Indicates whether CA Dynam/T will modify the DTF
file name at OPEN.
AUTOSCR or NOAUTOSC
Causes CA Dynam/T to analyze (or not to analyze) this
dataset for versions eligible to be scratched at every
close for output. Valid only for single file tape datasets,
the processing of this option is also dependent upon the
setting of the AUTOSCR parameter in the DYNAM/T
option record. If specified, the CADT064I message will
be issued whenever a version is scratched due to
AUTOSCR.
ROTATE or NOROTATE
Indicates whether CA Dynam/T will process tapes within
this dataset in a cyclical fashion, so that the newest
output version will be written over the oldest version of
the dataset, if the number of versions specified by the
NGEN parameter for the dataset is filled. All expiration
and retention criteria are ignored when rotating. That is,
even if EXPDATE=PERM, the oldest version will be
scratched.
When the first file of a multifile set is reused, all the
subsequent files are scratched. Therefore, if a multifile,
multivolume set is being rotated, all the volumes not
reused by the first file, are returned to the scratch pool
and will not be called when creating the subsequent files
of the multifile set.
LABEL or NOLABEL
Causes CA Dynam/T to process tapes within this dataset
as labeled or unlabeled.
