Chapter 6. BIM-EPIC DD Statements 6-3
DD Statement Syntax
You can specify multiple parameters after the DD operation. Some parameters have multiple
subparameters. Separate multiple parameters and subparameters with commas. Enclose
multiple subparameters in parentheses.
Many subparameters are positional. If you omit a subparameter, a comma must be specified
in the omitted position for all but the last subparameter, just as in VSE and MVS.
* //SYS007 DD DSN=SORTWK,UNIT=SYSDA,DISP=(NEW,DELETE),
* // SPACE=(TRK,(5,5),RLSE),VOL=SER=DOSRES
VOL=(,RETAIN,,,REF=*.TAPEOUT)
All DD statements and continuations can extend through column 71.
* //
ddname
DD
parameter
,...,

,
* //

,...,
parameter
Interrupt the current statement before column 71. The break must occur on a keyword
boundary. Do not split subparameters. End the statement with a comma. Do not specify a
comment after the comma.
Begin the next statement with the statement identifier '* //' in columns 1-4. Omit ddname and
the DD operation code.
In MVS, the first parameter in a continuation line must begin in or before column 16. If you
are specifying a BIM-EPIC DD statement for conversion to MVS, begin your VSE
continuations in or before column 18 to maintain compatibility. To move the statement to
MVS, delete the asterisk and the space that follows it ('* '), shifting the rest of the statement
two columns to the left.
* //SYS007 DD DSN=SORTWK,DISP=(NEW,DELETE),
* // UNIT=SYSDA,VOL=SER=DOSRES,
* // SPACE=(TRK,(5,5),RLSE)
To take advantage of BIM-EPIC's dataset drop option, use multiple DD statements with the
same ddname. No special coding is required. This is not valid under MVS. In addition,
VSAM datasets (including VSAM-managed SAM datasets) are not eligible for dataset drop.
Do not insert any other JCL, including * comment statements between the DD
statements that are part of the "Dataset Drop" set.
