Running DSNTIAUL using IKJEFT01 for batch unload

DSNTIAUL (an assembler program used to process select statements dynamically) is used to unload the tables, or to get the results of an SQL select in the unload format.

No details about the query will be displayed, just the resultset will be in the SYSPRINT.

Unloading the whole table. 

//STEP0001 EXEC PGM=IKJEFT01
//STEPLIB  DD DISP=SHR,
//            DSN='SSID.SDSNLOAD'
//SYSTSPRT DD SYSOUT=*
//SYSPRINT DD DISP=(NEW,CATLG,DELETE),
//            SPACE=(CYL,(250,100),RLSE),
//            UNIT=DISK,
//            DCB=(RECFM=FB,LRECL=80,BLKSIZE=0),
//            DSN=TEST.MYDSN
//SYSUDUMP DD SYSOUT=*
//SYSTERM  DD SYSOUT=*
//SYSTSOUT DD SYSOUT=*
//SYSTSIN  DD *
  DSN SYSTEM(SSID)
  RUN PROGRAM(DSNTIAUL) PLAN(DSNTIAUL)
  LIB ('SSID.SDSNLOAD')
/*
//SYSIN    DD *
SYSIBM.SYSDUMMY1
/*

Unloading a specific SQL select.

//STEP0001 EXEC PGM=IKJEFT01
//STEPLIB  DD DISP=SHR,
//            DSN='SSID.SDSNLOAD'
//SYSTSPRT DD SYSOUT=*
//SYSPRINT DD DISP=(NEW,CATLG,DELETE),
//            SPACE=(CYL,(250,100),RLSE),
//            UNIT=DISK,
//            DCB=(RECFM=FB,LRECL=80,BLKSIZE=0),
//            DSN=TEST.MYDSN
//SYSUDUMP DD SYSOUT=*
//SYSTERM  DD SYSOUT=*
//SYSTSOUT DD SYSOUT=*
//SYSTSIN  DD *
  DSN SYSTEM(SSID)
  RUN PROGRAM(DSNTIAUL) PLAN(DSNTIAUL) PARMS('SQL,1') –
  LIB ('SSID.SDSNLOAD')
/*
//SYSIN    DD *
SELECT * FROM SYSIBM.SYSDUMMY1
/*

The Parm ‘SQL,1’ says that I am giving an SQL statement and fetch only one record from the resultset into SYSPRINT.
