I had a couple hints typed out earlier, but given Meat187's post in the meantime, I will just say this: keep his points in mind and you will be on the right track.

- In the first segment I count 1006 symbols "+", "-", "." and "*". That number can't be divided by 3, 4 or 5 which means it's not a simple code replacing letters with a fixed length symbol representation.
- For variable-length codes you need to knwo where a unit begins. For this one can use a prefix-free code or a separator.
- Since the only combination that never occurs is ".." it's likely that the "." is such a separator.
- A typical variable length code is the Huffman Coding.
- If the meaning of specific code chunks doesn't change then it can usually be cracked using the Letter frequency. If the meaning of a chunk varies then it's a lot more difficult.
