LRECL=
MF=
Optional parameter. Specifies to CA Dynam/FI the logical record length for the
file. The DTF for the file will be modified. For more information about the effect
of this parameter, see the chapter "Controlling File Independence." Valid entry
is a 1- to 5-digit number in the range 1 to 65535.
Optional parameter. Specifies that the dataset is to be an automatic multifile
dataset. The only valid input is:
AUTO
Indicates that the dataset is an automatic multifile
dataset.
MINDEX=
MINDEX=(volser,unit,q1,q2,SYSnnn)
Optional parameter. Specifies the allocation characteristics of the master index
extent to be generated for the (ISAM) disk dataset if it is to be allocated by CA
Dynam/D. Valid entries are the same as for the PRIME data allocation (except
for the sequence option).
MODEL=
Optional parameter. Copies a dataset definition. The new dataset will be
defined with the same attributes as the specified model dataset. The only valid
entry is a 1- to 44-character data set name, enclosed in apostrophes.
Do not include any other operands when specifying MODEL with the DEFINE
command.
NGEN=
Optional parameter. Specifies the number of generations to be saved for this
dataset. For tape files, the number is the minimum number of cycles to be
retained, i.e., the SCRATCH function will never scratch any tapes belonging to
a version less than or equal to this value.
For disk datasets, this number represents the maximum number of
generations to be retained, i.e., CA Dynam/D will delete a generation from the
VTOC when a new generation is created which results in one more generation
existing on disk than is specified by NGEN. It is recommended that disk
generations to be controlled in this fashion be created using an expiration date
of RETAIN, to assure that they will not be inadvertently deleted by the
operator during space recovery. Valid entries are:
a 1- to 3-digit number in the range 0-999 for tape or disk datasets.
NOACC=
Optional parameter. Specifies the number of days a version is to be retained
after last access before it becomes eligible for scratch.
