| I have a GDG which has around 25 generations. I need to feed only the latest 13 generations of the same GDG to a program. Is there any method to feed these versions in a single DD statement? |

Aren't you familiar with dataset concatenation?
//DDNAME DD DSN=MY.GDG(0)
// DD DSN=MY.GDG(-1)
// DD DSN=MY.GDG(-2)
...
// DD DSN=MY.GDG(-12) |

| You can concatenate the 13 generations together but as far as I know you can only specify a single generation or ALL generations in one DD statement. |

This NO is for a portion of a post which has been deleted from the original post. |

Anand,
Since u need to use only latest 13 generation of GDG, you can concatenate that in single DD statement
ie
| Code: |
//ddname DD DSN=GDG 1
// DD DSN=GDG 2
.

Kevin,

| Huh? You mean my example won't work? |
It would work for sure.
The confusion is because
OP had asked whether he can code as shown below
| Code: |
| //DDNAME DD DSN=MY.GDG(0-13) |
For which gicchet replied NO. The NO is not for your POST which had the example of concatenation.
Hope it is clear now. |

Hi,
in order to concatenate multiple files you need more than 1 DD statement,
hence my answer still stands, it cannot be done with just 1 DD statement.

Technically speaking Gerry, you are perfectly correct 
One DDNAME can have multiple DD statements concatenated. |
