Gathering Field Descriptions From SAP

I am at the documentation stage of our project and I need Field Descriptions. They have been defined in SAP R/3 (DB2) and I can view them using SE11 command line parameter (It may change fom version to version, I don't know. It is the place where you view tables).
Lets say table X have 10 columns and every column's description has already been entered in SAP. In my situation there is a total amount of 200 tables which comes out appr. 2000 descriptions in return.
My question is as you may guess, Is there a way to gather this descriptions in a form of table(s)? So I can easily use this info for documentation. It maybe a third party tool or a command or a script wahatever. I really need this.

Thanks in advance.I have forgotten to tell that I am using SQL SERVER 2000 and connecting to DB2 via ODBC driver (though it is so slow...).
