Hello Ben, Thank you for providing the example cdl file; I've looked at it, and with input from one of our other developers (Russ Rew), we have determined that there are a couple of issues which would cause a larger size. However, the dominant factor is as follows: The 'string' data type is meant primarily for variable length strings, not individual characters. As currently constructed, every character (A, T, O, M, " ", etc) is being stored as an individual variable-length string. This is vastly inflating the size of the file. You *could* change the dimensions so that you have a 1D array of strings; this will give you a smaller file, but we can do better. If you change the record variable type from 'string' to 'char', and then replace the double-quotes (denoting a string) with single quotes (denoting a character), you will see the binary file size drop to 24K, far smaller than the original cdl file. I've attached an example of this to this message. Let me know if this works for you, or if you have any additional questions!
