Associates a DD name with a dataset.

Syntax:

      *---------------------------------------------------------------
      *--- DLBL OPERANDS
      *--- // DLBL filename
      *---          file-id
      *---          date
      *---          codes
      *---          DSF
      *---          BLKSIZE
      *---          BUFND
      *---          BUFNI
      *---          BUFSP
      *---          CAT
      *- --         CISZ
      *- --         DISP
      *---          RECORDS
      *---          RECSIZE
      *---------------------------------------------------------------

Where:

Operand		Description
filename		DD name
file-id		A unique name which identifies a dataset in the system catalog DSNs that start with a $$$ prefix are treated as temporary ones - for example: // DLBL `filename`, '$$$.`xxx`.`yyyy`'
date		Retention period in days (0 to 9999) or Julian date
codes	Parsed but not processed*	VSAM SD or DA
DSF	Parsed but not processed*	A data-secured file
BLKSIZE		Block size
BUFND	Parsed but not processed*	Number of I/O buffers
BUFNI	Parsed but not processed*	Number of index buffers
BUFSP	Parsed but not processed*	Number of bytes allocated for buffer space.
CAT	Parsed but not processed*	Catalog name; single system catalog in MF
CISZ	Parsed but not processed*	Control Interval size
DISP		Disposition opened, after normal step end, after abnormal step end
RECORDS	Parsed but not processed*	Number of records for primary and secondary space allocation
RECSIZE		Average record length

Note: The command and operand combinations listed in these topics are supported unless indicated as "parsed but not processed". Where indicated, this means:

Parsed but not processed - indicates that the command and the operand are not supported, however, Enterprise Developer parses it and, if it fails validation, a JCL error is generated.
Parsed but not processed* - indicates that a number of the operands for JCL and POWER commands (for example, any tape or volume-specific operands) do not apply in the Enterprise Developer environment. See General Differences.
