You can accomplish the task but it requires two job-steps, one conditional
(the RENAME), as shown below.

//STEP1    EXEC SAS

//SYSIN    DD   *
%MACRO X;
DATA _NULL_;
%IF %SYSFUNC(FILEREF(INPUT)) %THEN
PUT '>INFO>  NOT IN JCL.';
%ELSE
ABORT RETURN 4;
RUN;
%MEND X;
%X;
//         IF RC > 0 THEN
//* ONLY EXECUTE RENAME, IF DSN ALLOCATED IN PRIOR SAS STEP,
//* INDICATED BY COND CODE 0004.
//STEP1    EXEC PGM=IKJEFT01

Hi JCL Friends,

It would be a great help if u could solve my problem.

Following is the problem i do have....

Before reading or creating any dataset in the program i want to check
whether the particular dataset exist or not.IS there any function to
check whether the dataset exist or not.

The following is the stuff i want to do.

If the dataset exist then rename dataset X to y,and continue with the
remaining statements.

If the dataset doesn't exist then write the dataset doesn't
exist...then comeout of the program.


Thanks a lot well in advance.
