Heres a great parser I found (not sure who wrote it but cheers to them) that parses db2 files to .csv and also another tool to convert the csv back into a dbc file. Might have even more parameters… I just found it and decided to share if anyone was looking for something similar. https://drive.google.com/open?id=0Bx9PAVqeiO8ocmx0MFlSa2ZmQTA The zip file also includes the current 6.2.3 db2 files already in csv format.
