Yeah, I'm already using a character prefix for header data in the 1st file. Right now, one of the headers tells where to find the 2nd file. Seems to be working okay. I'm a little bothered by the idea of lumping both into one dictionary, though I see this could be done the same way. I wasn't really looking for a way to compress the data (just thought it was a nice side benefit), but your post reminded me that I could do it with zlib on the data *before* storing them in the shelf. I guess if bulk becomes an issue I'll try that. -- Terry Hancock ( hancock at anansispaceworks.com ) Anansi Spaceworks http://www.anansispaceworks.com -- http://mail.python.org/mailman/listinfo/python-list
