2. Specify whether to include debugging comments in the generated JCL:

   Important

   We  recommend that you include the comments if you suspect that the JCL was generated incorrectly and you need to send documentation to Customer Support. If you want to reduce the number of lines of JCL, do not include the comments.

   1. In the Include data set sizing comments in JCL field, type Y or N to specify whether to include comments in the generated JCL that show statistics for determining data set sizes.Comments are shown as dsso/cc, where dsso is the data set sizing option and cc is a comment code. The following table lists the comment codes that Execution generates in the JCL.

      Comment codes for data set sizing 

      Data set sizing options	Comment code	Description
      B, C, or O	C	Uses statistics from the DB2 catalog
      	H	Uses the high relative-byte address (RBA)
      	M	Uses multiple objects to size one data set (for example, SYSUTs)
      	N	Indicates that the data set could not be sized because statistics could not be found
      	O	Uses VSAM object sampling
      	S	Uses the following formula to calculate the SORTWK size: (work space * 2) / number of SORTWK data sets
      	W	Warns that the sizing might be inaccurate

      The following figure shows example comments in the Execution JCL.

      //         DISP=(NEW,CATLG,CATLG),
      //         SPACE=(CYL,(10,2),RLSE), ESTIMATE-B/N

      //SORTWK01 DD UNIT=SYSDA,
      //         SPACE=(CYL,(1,1)),   ESTIMATE-C/S
      //         DISP=(NEW,DELETE)
   2. In the Include variable substitution comments in JCL field, type Y or N to specify whether to include comments that show the SLIB variables and their assigned values.JCL Generation uses these variables to resolve the names of the data sets in the generated JCL.

3. In the Suppress comments in JCL field, type Y or N to specify whether to suppress all comments in the generated JCL.

   Important

   If you chose to include either the statistics comments or the variable comments in Step 2 (above), you cannot select to suppress all comments in the JCL.

4. In the Specify an Alternate Program for IKJEFT01 field, type the name of a program to be used instead of IKJEFT01.

   Important

   The alternate program is only used for nonworklist JCL.

5. In the Specify a Plan name to run DSNTIAD field, type the name of the Db2 plan to run the IBM DSNTIAD program.
6. In the Pre Job Step JCL INCLUDE member name field, type the name of a JCL member to be included before each step in the JCL.
7. In the Post Step JCL INCLUDE member name field, type the name of a JCL member to be included after each step in the JCL.
8. In the Post Job JCL INCLUDE member name field, type the name of a JCL member to be included at the end of a job.
9. For each AEXIN keyword, type Y or N to specify whether to include the keyword in the AEXIN input stream.For more information about the keywords, see Keywords-for-input-streams.
10. Press END to save your changes and return to the DASD MANAGER PLUS Main Menu.
