I have also triedf all the ways to Pass this Infile to Natural (Using PARM, STACK) but i am unable to do this. So, thought of other options like, can get the Infile name captured within the JCL (In just prior step to my natural) so that i could copy that to an Work File and then i can read the work file from natural in the next step and get this Infile value there.

You can invoke LISTALC directly from within Natural (Using the TSO example in the supplied example library).

If you decide to retrieve the dataset name in a separate step (prior to Natural), you can later pass the value using work file.

BTW - from my experience, Natural won't be the first choice for HUGE file processing, simply because it is interpreted. SORT would do a much quicker job.

How about making the DSN be a symbolic and STEP5 can receive it as a PARM rather than read a file?
Code:
//MYNAME  SET  DSNAME3=MY.DATASET.NAME
//STEP03   EXEC PGM=Whatever
//DDNAME   DD DSN=&dsname3,DISP=(,CATLG,DELETE),
//           ...... etc etc

//STEP05   EXEC PGM=Whatever2,PARM='&dsname3'

Also, please remember that most IDCAMS opreations can be specified with DDNAME, not just DSNAME.

Well it would be nice to tell us your solution.
Everybody wants to know of course if his/her input was part of it.
