I have a code in Assembler in which a file is being dynamically created. The code is running fine in production creating a new file. But I wanted to modify the code so that I should add a Retention period for the dynamically for the newly created file. I tried giving the RETPD for the file in JCL but that doesnt turn to work out as the file is getting creted dynamically.
The portion in the code where the file is allocated dynamically is:

and my Storage Declarations are in the attachment (Definitions.txt). I have also attached the above code (DYNALLOC.txt).
I could see the parameters passed to this file like DISP, VOLUME are passed with some hex values like X'02' and X'04'.
I am not familiar much on Dynamic file handling in Assembler. Any help to add a RETPD parameter of 2 days to the above code would be really grateful.
