Hi,
I want to insert delete step in a JCL for which i have created a tool, but if suppose the dataset name is having symbolic parameters like &HLQ..&SS&ENV..JCL then i will have to change all those parameters and then use that dataset name in my delete step....how do i convert all those symbolic parameters into normal dataset and use it....can some please suggest me some idea of how to achieve this....

What is the issue in using IEFBR14?

Otherwise you can take all those symbolic parameters from your proc components and define the same in your rexx tool. This way you can replace everything in your tool itself.

Post the code so we will get the right picture.

In the code i will capture the dataset name and move it to stem variable by using which i will insert the delete step....But now my requirement is :
I will be having Symbolic parameters like &HLQ..&SS&ENV..JCL instead of mentioning it as TTE.IDFG.JCL i would have used SET statement for each qualifier so when i capture the dataset name by using my tool it would have been captured as &HLQ..&SS&ENV..JCL but i want it to be captured as TTE.IDFG.JCL ....how do i change each qualifier and capture it to insert the delete step in my JCL.....some please give me idea for achieving that.....

If you use IEFBR14 instead of IDCAMS, and use MOD,DELETE,DELETE disp parameter for each dataset, I guess you may not have to worry about sybmolic parms. You can use the same JCLLIB ORDER and INCLUDE in the job with IEFBR14 and do not worry about symbolic parms

i think you dont understand what i am trying to say.....Already there is a JCL with some nrely created files in it....so each when i run the JCL i have to delte those files..instead of doing that i decided to add the delete step with all the newly created DSN and delete it each time when the JCL is run....so in that how can i use IEFBR14 for deleting all the Dataset at the same time in a single step.....for that purpose only i have used IDCAMS to include in my JCL.....If suppose i have used some 100 newly creating Dataset in my JCL and while runnign the JCL each time i have to delte all those datasets so i am inserting this IDCAMS steps containing the delete dataset name of all those 100 newly creating datasets....since it is difficult to enter manually for all those 100 i created rexx tool for inserting that step by capturing the newly creating dataset alone from my JCL and writing delete dataset step using IDCAMS.....but if suppose i have specified my dataset name with symbolic parameter.....then capturing that DS and writing the delete step will be of no use so how do i change those DS containing the symbolic parameter to normal one and write the delete step.....

Code:

//        SPACE=(TRK,(1,2),RLSE),
//        DCB=(LRECL=80,RECFM=FB,BLKSIZE=800)




This is how my JCL will look like when i execute the above rexx tool....so my delete step using IDCAMS is inserted in the JCL....but what if i use symbolic parameter how should i change it.....

You can delete any number of datasets in same IEFBR14 step. All you need to do is define all those datasets as DD statements automatically using REXX.
If you want you can also code ADDRESS TSO DELETE 'data set name' line in your rexx code and remove all those IDCAMS steps. This will directly delete the datasets within rexx code.

a little tweek in your code:
Code:

I=1
"ISREDIT LINE_BEFORE .ZCSR = '//JS0010 EXEC PGM=IEFBR14"
"ISREDIT LINE_BEFORE .ZCSR = '//SYSPRINT DD SYSOUT=*'"
"ISREDIT LINE_BEFORE .ZCSR = '//SYSOUT DD SYSOUT=*'"
DO WHILE INSLIN > 0
OUT="//DD"||I||"   DISP=(MOD,DELETE,DELETE),DSN="||OUTPUT.I
"ISREDIT LINE_BEFORE .ZCSR = '"OUT"' "
INSLIN=INSLIN-1
I=I+1
END
[/code]

if You are able to get the proper authorizations to install it and use it
look at Gilbert Saint Flour ( RIP ) freeware

http://www.gsf-soft.com/Freeware/

for the cleanup program

Quote:
CLEANUP Assembler program. Automatically searches the MVS
catalog for non-GDG data sets that will be created
in subsequent steps of your job and deletes them.
HSM-migrated data sets are deleted with HDELETE.

//MYJOB JOB acct#
//*
//CLEANUP EXEC PGM=CLEANUP
//*
//STEP1 EXEC PGM=MYPROG1
//OUTDD DD DSN=MY.FILE1,DISP=(,CATLG)
//STEP2 EXEC PGM=MYPROG2
//OUTDD DD DSN=MY.FILE2,DISP=(,CATLG)

Can also be executed as the LAST step of a job to
delete non-GDG data sets that were created during
job execution.


very reliable ...
started using it more than 10 years ago and survived all the operating systems migrations

Hi,
Thank you for helping me with the code what you said is right i can do the same process with IEFBR14.....But the project which i work in uses always IDCAMS for delete i dont whether they will accept this or not....I also have a doubt here....If i use IEFBR14 how do you say that it will delete properly even if i use symbolic parameter.....

Hello,

You can delete any number of datasets in same IEFBR14 step.
Well, not quite . . . . If you try too many, it will fail.

The max is over 3000. And i do not believe we need another rambling of just how many DDs are ok "depending". icon_cool.gif

In case of IDCAMS you are coding dataset names with symbolic parameters inside SYSIN DD *, and these variables will not expand when used within SYSIN DD *. In case of IEFBR14, this will not be the case as dataset names are coded in DD statements.

rightly said. You can run your code with both IEFBR14 and IDCAMS and see for yourself how both utilities work.

That's why I asked what scheduler he used, but I did not get a reply.

Hi,
I am in need of using only IDCAMS in my code as we are not allowed to used IEFBR14 in delete step in our working environment.....so kindly help me with this problem to solve the issue by using IDCAMS itself...
