DLBL Options

Aligns the disk allocation on cylinder boundaries. Valid for CKD devices only. Allocations

for direct access (DA) and ISAM datasets are aligned automatically.

Changes the block size of your datasets without recompiling your programs. Valid for

datasets with either fixed or variable record formats. Reblock with caution when running

programs that use physical IOCS; such programs must be able to support reblocking. Specify

a numeric block size, MAX for full-track blocking, or OPT for half-track blocking.

Puts the version in the DSN Catalog in conditional catalog status.

Deletes the dataset after it is closed as input. It is not required for compiler work areas or

SORTWK files (they are deleted automatically).

Invokes dataset concatenation, which causes the problem program to read two or more files as

if they were a single file (using just one open and one close). Dataset concatenation can only

be performed for cataloged datasets. Dataset concatenation differs from dataset drop (option

'T') in that dataset drop only processes one dataset when a single open is issued by the

program.

When the requested amount of space is not available, this option allows BIM-EPIC to allocate

the largest available contiguous space. Do not use for TYPEFLE=WORK files (for example,

compiler work areas and FORTRAN disk files) or for any other files that do not support

secondary extents. If you do not specify the F option, and BIM-EPIC cannot find the

requested contiguous extent in the pool, message EP038 is issued, to which operator can

respond FRAG to invoke fragmentation.

Accesses the specified generation of the dataset. This is useful when you want to access a

specific version of a dataset without reference to its relative version number. The generation

number of a version is listed in the TSIDUTL DSPLY and catalog maintenance DISPLAY

reports. It is valid for cataloged datasets only.

Overrides the configuration option FRAG=YES, preventing automatic file fragmentation if the

space requested for allocation is not available. The EP038 message is issued, so FRAG can

still be specified in reply to continue the allocation.
