If you want to get this information through dbc metadata tables then as Dieter mentioned, it is not possible to get all 'possible' parameter information.
You can get the latest table defintion using SHOW command, and teradata returns the result the table definition in a standard format. So you can probably write some code in an external language and compare the get the table definitions and compare the strings.
I haven't tried this myself, but I guess this should solve your problem!
