DD Statement Syntax Specifying the DD Statement

6-4 User Reference

* //TAPEIN DD DSN=INVENTRY.1QTR(0),DISP=(OLD,KEEP)

* //TAPEIN DD DSN=INVENTRY.2QTR(0),DISP=(OLD,KEEP)

* //TAPEIN DD DSN=INVENTRY.3QTR(0),DISP=(OLD,KEEP)

BIM-EPIC concatenates all versions of a single input dataset automatically, as does MVS. If

you do not specify a single version on input, all versions are read sequentially, beginning with

the current version.

* //TAPEIN DD DSN=INVENTRY.1QTR,DISP=(OLD,KEEP)

To concatenate several versions of the same dataset or several different datasets, use a DD

statement for each version or dataset and omit the ddname on all but the first statement.

Submit the statements in the order you want the datasets processed. If block sizes differ, the

version with the largest BLKSIZE must be specified first. VSAM datasets (including VSAM-

managed SAM datasets) are not eligible for concatenation.

Do not insert any other JCL, including * comment statements between the DD

statements that are part of the "Concatenating Datasets" set.

* //TAPEIN DD DSN=INVENTRY.1QTR(0),DISP=(OLD,KEEP)

* // DD DSN=INVENTRY.2QTR(0),DISP=(OLD,KEEP)

* // DD DSN=INVENTRY.3QTR(0),DISP=(OLD,KEEP)

You can have BIM-EPIC check the syntax of DD statements before you run the job. Place a

TYPRUN=SCAN or TYPRUN=SCANS parameter on your JOB statement. See TYPRUN

for details.
