What format to use to store expressions in database? It's a requirement that {_String, _Real} should not be split into two columns. Sorry if I'm not clear with that. Also, the depth and length of the list is indefinite. So separating it is not generally possible. |

How to let output and message be print to two separate external files? No. I don't know exactly all the details of the program I'm running. But I'm guessing, it's trying to print something whose up value isn't defined for OutputForm. |
