Anne,
Use IDCAMS and create the cluster. Let us know, if you need the control card. |

Hello,
A good way to get yourself a set of control statements is to find the VSAM definition of a similar file at your location.
Once you have that control info, use it and the IDCAMS manual to build the statements for your new vsam file.
When you have questions, we're here. |

The control statements are easy, but you do need to know about the VSAM file that you want.
a) What name do you want to call your cluster
b) What will the file be used for, DB2, IMS, general data
c) Does it require an index
d) Where is the key and how long is the key
e) Is it a fixed length file or variable length
f) What are the record length(s), average and maximum
g) Will you be doing inserts into the file if indexed
h) How many records will it hold
i) Will it require an alternate index |

expat,
That will confuse the OP.
I think dick's advice will suit the most for OP.

To add little bit -
If your site has FILE-AID then it is the easiest way to copy attributes of existing VSAM dataset. (IMHO  ) |

Maybe, but in my view these are the basic requirements for knowing how to define your files correctly. If the person wanting to allocate the file can not answer 80% of the questions, I'm not sure I would like them logging into my system. |

Fear, uncertainty and doubt, a marketing strategy.
Ask william, he used it once...
I forgot 'my $0.02' in my last post. |
