Changing a SYSIN Control card in Runtime...

Hi
I want to change a control card in runtime . I want to change the filename(present in SYSIN card) when the same job runs twice in a day or particular time span. I wanted to know whether changing the control card like this is possible or not and if yes then how can I do it?

What program / utility is being processed
What are you using this program utility to do
What changes do you want to make

Psychic day was yesterday so please post an example of what you have and what you want to change it to.

HI
I am using SYSIN card for FTP step. I wanted to avoid overwriting of file mentioned in SYSIN after each run. For that I want to change that filename in every next run. The SYSIN for FTP step :

I know this is impossible but just wanted to double check with others...

You could over-write the dataset containing the FTP Control Cards or use and include in your JCL and over-write the contents of the include. For either of these you may/would need to write back the old contents the next day. Just thinking outside the box.

Hello Swapnil,

If you know the rule for the FILENAMEs and allowed to change the JCL, why don't you put the new COBOL (or whatever easy for you) step that creates/changes the SYSIN dataset for next FTP run.

Alternatively, COBOL program can execute TSO commands which include FTP, please google it if you want to change the FILENAME dynamically inside of the program.

Thanks,

Hi
I have tried to change the filename dynamically in SMTP step using Symbolic variables. Unfortunately we cannot test FTP so may I know whether the same symbolic variables are valid in FTP also.
Here is the manual I referred :

I tried this thing :

Hello Swapnil,

I am wondering the issue has been resolved.
Have you tried that Douglas and I suggested?

Thanks,
Dominic

Hi dominickim,
We cannot test FTP in test region. We are trying to get access for it.. That's why I want some surety that same symbolic variable will work in FTP also so that I can persuade upper management for access.
Please let me know whether it will work in FTP or not??
Thanks for your suggestion...

Hello Swapnil,

First of all, the &TIME is not valid symbolic name.
Second, symbolic variables can not be overwritten if it placed inside of SYSIN cards that system does not consider as part of JCL.

Thanks,
Dominic

This is a method commonly followed in my shop.

Step 0. Delete temporary FTP file
Step 1. Read the FTP card and change the file name and write into a temporary FTP file.
Step 2. FTP using temporary file.

Step 1. Read the FTP card and change the file name and write into a temporary FTP file.

This step needs to be done using a program or a sort card or whatvere normal data processing utility.

Hello Abin,

That's exactly what we are using, too and I suggested earlier.
Thanks for your details.

Thanks,
Dominic

This is exactly an issue we faced sometime back,

what we have done is we generated the FTP control card having date and time appended to the destination file name like the one below shown below
using a sort card
