| I need to process all the generations of a GDG one by one, I do not want to code a step for each generation , is there a way by which I can code only a single step? |

How do you mean one by one.
Do you mean that you want to process all existing generations en mass, i.e. all existing versions get processed within the same process in one pass or that each individual generation must be uniquely processed ? |

You can catalog successive updates or generations of related data. They are called generation data groups (GDGs). Each data set within a GDG is called a generation data set (GDS) or generation. If the attributes and organizations of all generations in a group are identical, the generations can be retrieved together as a single data set.

From Chapter 29. Processing Generation Data Groups of the z/OS V1R7.0 DFSMS Using Data Sets manual. |

Then unfortunately I believe that the time spent analysing and coding the solution to this would probably be much more than amending the JCL and submitting the job numerous times. |
