Creating the sample data sets

Many of the examples in this document use A123456.SORT.SAMPIN, A123456.SORT.SAMPADD, and A123456.SORT.BRANCH as input data sets, and A123456.SORT.SAMPOUT as an output data set. If you want to try the examples in this document that use these data sets, create your own userid.SORT.SAMPIN, userid.SORT.SAMPADD, userid.SORT.BRANCH and userid.SORT.SAMPOUT data sets with your own userid by running the ICEDCRE job that follows.

Substitute your own JOB statement for the ICEDCRE JOB statement. Substitute your own userid for 'userid' in the four DD statements.

If you use a JOBLIB or STEPLIB to run DFSORT jobs, add it to the ICEDCRE job. If you prefer a value for UNIT other than SYSALLDA, change that parameter in the DD statements. Add a VOL=SER=vvvvvv parameter to the DD statements, if appropriate.

//ICEDCRE  JOB A492,PROGRAMMER
//SAMPCOPY EXEC PGM=ICESAMP,PARM=(BOOKS)
//SYSPRINT DD   SYSOUT=*
//SAMPLE   DD   DSN=userid.SORT.SAMPIN,DISP=(NEW,CATLG),
//         SPACE=(TRK,(1,1),RLSE),
//         DCB=(RECFM=FB,LRECL=173,BLKSIZE=1730),
//         UNIT=SYSALLDA
//*
//ADD      DD   DSN=userid.SORT.SAMPADD,DISP=(NEW,CATLG),
//         SPACE=(TRK,(1,1),RLSE),
//         DCB=(RECFM=FB,LRECL=173,BLKSIZE=1730),
//         UNIT=SYSALLDA
//*
//OUTPUT   DD   DSN=userid.SORT.SAMPOUT,DISP=(NEW,CATLG),
//         SPACE=(TRK,(1,1),RLSE),
//         DCB=(RECFM=FB,LRECL=173,BLKSIZE=1730),
//         UNIT=SYSALLDA
//*
//BRANCH   DD   DSN=userid.SORT.BRANCH,DISP=(NEW,CATLG),
//         SPACE=(TRK,(1,1),RLSE),
//         DCB=(RECFM=FB,LRECL=33,BLKSIZE=330),
//         UNIT=SYSALLDA
//*
//SYSIN    DD   DUMMY

Once you run this job successfully, you can substitute your userid for A123456 in the data set names of these four data sets. For example, if you see a DD statement like this:

//SORTIN DD DSN=A123456.SORT.SAMPIN,DISP=SHR

you can use your own DD statement like this:

//SORTIN DD DSN=userid.SORT.SAMPIN,DISP=SHR

Note: Some of the examples use data sets other than A123456.SORT.SAMPIN, A123456.SORT.SAMPOUT, A123456.SORT.SAMPADD, and A123456.SORT.BRANCH. You can either create data sets from scratch to match the ones used in the text, or else perform a similar exercise on data sets you already have.
