GDG versions in a JCL

There is a JCL which has three steps.

Step 1:

It uses the GDG(0) as input and creates another GDG version.

INPUT - GDG(0)
OUTPUT- GDG version created by step 1

Step 2:

It uses GDG(0) and the output of step 1 as input and creates another GDG version.

INPUT  - GDG(0) and Output GDG version created by step 1
OUTPUT - GDG version created by step 2

Step 3:

It uses the GDG output created by Step 1 and step 2 as input and creates another GDG version.

INPUT  - GDG version created by step 1 and Step 2
OUTPUT - GDG version created by step 3


First question:

What are the version numbers used and created by each step?

"; ; ; ;

Second Question:

If JCL abends after successful execution of Step 2, and needs to be restarted from Step 3, are there
any changes required in the GDG version numbers used in Step 3.

gdg question
How many forums do you plan on posting the same question? This is rather inconsiderate if not just plain rude. As you were told there, STOP using the term Version. While there is a "version" you will probably never create a new one as an application developer. All of what you asked is completely answered in your other topic. . .
