Not to knock batch file programming (there's some really impressive stuff you can do, lots of enthusiasts out there), but if this is a windows environment wouldn't VBScript (run using CScript.exe, from the command-line) be acceptable? This gives you nice error-handling, backwards compatibility to at least w2k & SQL2K, very easy access to any com objects (DMO or SMO), etc.
Of course, that's without going into the new fancy powershell stuff 🙂
