hi all,
Suppose i have 100 concatenated datsets as shown in the below eg..Is it possible to override the 50th dataset without disturbing the other datasets,If so do mention the procedure for it.Here infile50 should be replaced with infileA

eg:// step10 exec pgm=xxxx
// infile dd dsn=infile1
// dd dsn=infile2
// . .
// . .
// dd dsn=infile50 <----
// . .
// . .
// dd dsn=infile100

The answer is right there... in the fine manual.

Hi Manasa,

You can use the symbolic parameter for this particular dsn name in the concatenated datasets' list. When you call the procedure in the job, provide the actual dataset name.

eg:

//PROCA PROC
//PSTEP1 EXEC...
//DD1 DD DSN=DSN1,DISP=SHR
// DD DSN=DSN2,DISP=SHR
// DD DSN=&&DSN3,DISP=SHR
// DD DSN=DSN4,DISP=SHR
.
.
.
// PEND

In the job,

//JOBSTEP EXEC PROCA,DSN3=actual dataset name
