with the SPACE control dataset.
If used, specify one of the following (optional):
CONTIG No None

ALX No None
ROUND No None
Subparameter Required? Default
Subparameter Definition
type Specifies type of allocation.
TRK Specifies allocation in tracks or FBA blocks.
CYL Specifies allocation in cylinders and forces the
dataset to begin and end on cylinder boundaries.
block-length Specifies the block size of a dataset for allocation
by number of logical records (ALR). In addition,
block-length can used to specify the record
size of VSAM/SAM datasets.
size-spec Specifies size, is required and must be enclosed in
parentheses. Size-spec takes the form:
primary-qty[,secondary-qty][,index]
primary-qty Specifies the amount of the primary allocation in
tracks, FBA blocks, cylinders, or number of logical
records, depending on the value specified by type.
To use the SPACE parameter to indicate an option
for a cataloged dataset, such as fragmentation, no
truncation, or align on cylinder boundaries,
without affecting the allocation size, specify 0
(zero) in primary-qty. When primary-qty
is 0, BIM-EPIC uses the allocation size specified
in the dataset definition.
secondary-qty Specifies the size of secondary allocations. To
specify a maximum number of secondary
allocations, use the VOLUME.
index Specifies the size of the index component for an
ISAM dataset. Use index only when both the
prime area and the index area are defined with a
single set of parameters. If you use index but
omit secondary-qty, you must include a
comma for secondary-qty, since these
parameters are positional.
