A frequently asked question...
Admin Ref manual chapter 3, Redirecting Command Output addresses this.
And from my notes at http://people.bu.edu/rbs/ADSM.QuickFacts :

>                                       Redirection character in the server
                                        administrative command line interface,
                                        if at least one space on each side of
                                        it, saying to replace the specified
                                        output file.  There is no "escape"
                                        character to render this character
                                        "un-special", as a backslash does in
                                        Unix.  Thus, you should avoid coding
                                        " > " in an SQL statement: eliminate at
                                        least one space on either side of it.
