I do want to pass temporary dataset to second step without using disp=pass parameter.... as this is requirement ....

Requirement is :- Sysout data need to put to two places one in the dataset and another to the Jes output... so the option which i found is
//sysout dd dsn=&&temp,sysout=*

this way sysout will go to temporary dataset as well as to sysout class ... however we cann't use disp parameter here becoz of exclusive use ,, how can i use the temp dataset in the next step...??????????/

can i get ans asap

hav u used &&temp in ur subsequent step directly.. any error its throwing....

In my opinion, though u hvnt coded the disp, in sysout if u code &&xxx, its the last qualifier of the system generated dataset.

its like userid.jobname.jobid.Ddsnumber.xxx

kindly check & revert.

Shiva what will happen exactly This temporary dataset which ur saying (userid.jobname.jobid.Ddsnumber.xxx ) --which one is right would be created and deleted with in the step itself and if you will try to use the temp dataset in the next step it will say DATASET NOT FOUND .....

as to pass the temp dataset to next step we must need to code disp...

u can do that using the referback concept.In this case we do not have to mention the disp parameter

the referback statement can be used as folows
assume u have to use the temp dataset created in the first step in the second

in that case we use..

//step1 exec pgm=pgm1
//data dd.....
//step2 exec pgm=pgm2
//data2 dd *.step1.data1

In this way u will be accessing the temp dataset cteated in step1

for your information you even can't reference back temp dataset as it get deleted as the first step end....................

Anyway thankyou... as i m planning to use IEBGENER

to get my desire output...

temporary datasets dont get deleted after the execution of a step they are retained untill the end of the job.
If they get deleted why do u think they should be used and what purpose does it serve if a data set is just created for 1 step and that info cant be used anywhere.
please refer MVS JCL PRIMER- BY RANADE FOR THE CONCEPT.

Hi ravi,
Temporay datasets wont get deleted until the end of ur job and even if u dont code Disposition parameter for Temp dataset , MVS will internally take that as DISP=(NEW,PASS).

Thanx.

That's what i am saying,,

If you won't use DISP=NEW,PASS you can't use it in the next step...

let i give an example :-

/STEP1 EXEC PGM=CREATE
//DD4 DD DSNAME=&&ISDATA(PRIME),DISP=(,PASS),UNIT=(3350,2),
// VOLUME=SER=334859,SPACE=(CYL,(10,,2),,CONTIG),DCB=DSORG=IS
//STEP2 EXEC PGM=OPER
//DD5 DD DSNAME=*.STEP1.DD4,DISP=(OLD,DELETE)

here in the step1 we r creating one temp dataset which we are passing so with in the same job we can use it in any step using back reference.... however VIJAYA if you will not give disp=,pass U can't use it in the further step........ I HOPE IT IS CLEAR TO U BOTH...

Let me clear if i am wrong..
