Dear all,
Can you please guide me to dummy out multiple dataset using JCL.
Note: The dataset should not be delete.
Thanks in advance.

You need to show the JCL you have and what the modified JCL should look like.
I don't understand what you are asking.

Hi,
Please provide bit more clarity.
Do you want to empty out many datasets?
Thanks

Hi,
Yes Guru, I want to dummy out many dataset.
Dikduke and Guru please consider the below scenario.
10 dataset have to concatenate into GDG and that GDG is the input to the program. If the program runs successfully, at last all the 10 dataset should be dummied out (empty) to avoid the repeat records next time when interface trigger input to that 10 dataset.
Using which utility I can do it? help me on this.
Thanks

Hello,
Assuming the files that need to be emptied are FB, LRECL 80.
You could try this below code,
Code: Select all
//STEP0010 EXEC PGM=SORT
//SORTIN DD DUMMY,DCB=(LRECL=80,BLKSIZE=0,RECFM=FB)
//OUT1 DD DSN=WELLS.FILE.TO.BE.EMPTIED1,DISP=OLD
//OUT2 DD DSN=WELLS.FILE.TO.BE.EMPTIED2,DISP=OLD
//OUT3 DD DSN=WELLS.FILE.TO.BE.EMPTIED3,DISP=OLD
.
.
.
//OUT10 DD DSN=WELLS.FILE.TO.BE.EMPTIED10,DISP=OLD
//SYSOUT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//SYSIN DD *
SORT FIELDS=COPY
OUTFIL FNAMES=(OUT1,OUT2,OUT3.....OUT10)
//*
Hope it helps.

DUMMY and empty are two different concepts - did I miss something...

Hello Anuj, nice to see you here

Yup the TS seems to have mixed them up. I assumed the requirement was the empty the file and posted a snippet.

From what has been explained by TS, i believe there is at least some inconsistency. . .
What will happen with these files after they are "empty"?
Why empty them at all?
Obviously there is something i am missing.
