Hello, Thank you for the advice. I've done a fairly intricate series of SQL inner joins and aliases to have a Cartesian set of data match points into a csv exported file. I also know how to open two files and write into one.

I will look into the hash of hashes method to insert data into the LDIF formatted file. I have a similar routine in a previous script and what you said about the first layer & second layer keys make sense. Thanks again.
