Data Set Use

The Wizard Report Writer requires several interrelated files to execute. The following list describes these data sets and their functions.

DDName File Name	Description Of Use	Predefined DCB Attributes
CAIJSHST	Used to input IMS data produced by the Translate Utility.	RECFM, LRECL, and BLKSIZE set automatically
anyname	Output data set for summary file generated using the Summarization Feature.	RECFM, LRECL, and BLKSIZE set automatically
CAIJSACT	Optional output DD for EXTDATA (only). Data will be written if the DD exists in your JCL and there is a valid TRANSLATE command.	RECFM, LRECL, and BLKSIZE set automatically
SORTWKnn	Temporary data sets used as sort work area in sort phases.	RECFM, LRECL, and BLKSIZE set automatically
CAIJSCT1	Temporary data set to hold edited report control statements.	RECFM, LRECL, and BLKSIZE set automatically
CAIJSCT2	Same as CAIJSCT1	RECFM, LRECL, and BLKSIZE set automatically
CAIJSCIN	Used to input report control statements	RECFM=F, LRECL=80
CAIJSPRT	SYSOUT data set for output reports.	RECFM=F, LRECL=133

In addition to these data sets, the following files are required:

//STEPLIB   DD DSN=____,DISP=SHR,UNIT=____,VOL=SER=_____
//SORTLIB   DD DSN=SYS1.SORTLIB,DISP=SHR
//SYSOUT    DD SYSOUT=____
//SNAPDUMP  DD SYSOUT=____

The STEPLIB statement points to the DASD volume on which a partitioned data set (user library) resides that includes the Wizard Report Writer as a member. If the library has been cataloged on the system, then the unit parameter and volume identification are not necessary.

The SORTLIB statement is required during the sorting operations activated by the Wizard Report Writer. This data set contains modules which are essential to the execution of the program.

The SYSOUT statement provides an output data set for the messages displayed on the printer by the IBM or vendor-supplied sort/merge program. You should be aware that this ddname may vary from one installation to another depending on the options specified at the time the sort/merge program was installed. Typical substitute ddnames employed by users are SORTMSG, SYSPRINT, and so forth.
