Thinking about your query some more made me realize you didn't give us enough technical specifications to help you very much. E.g., what do you mean by "populate"? What do you mean by "contains" keys? Namely, will the data set be blocked or unblocked? If unblocked, you might even be able to use IEBGENER and specify the key location and offset through JCL. If blocked, then what does the block's key represent - the lowest key of any record in the block, the highest key of any record in the block, or something else? Must all the keys written onto the tracks be in ascending key sequence, descending, or is random OK? What will happen if there are two blocks somewhere in the data set with the same key? How will this data set be accessed after its creation? With what software and/or access method? What will said accessing programs do if a key is not found? What happens if a block is found with no key on the track? How long will this data set exist? How do you plan to back it up and restore it if necessary? Will it be automatically managed by some kind of archival system? I don't expect answers to all of these, but you definitely need to think about these issues. Bill Fairchild Rocket Software
