st: Strange Error Message in XTABOND

["Tim R. Sass" <tsass@coss.fsu.edu>]

I recently began using a newly installed copy of Stata for Unix (Ver. 
8.1).  I tried running a .do file that ran without error on my Windows 
version of Stata (Ver. 8.2).  The XTABOND command and error are:

xtabond nrtrscre charter chrtageb
        target convrt forprft
        nschools chgschl
        tgrde_06 tgrde_07 tgrde_08 tgrde_09 tgrde_10
        if cohort !=0, robust;

too many lags of the dependent variable requested
lags() must be beween 1 and 0
r(198);


I don't specify any explicit number of lags.  Isn't the default a 
once-lagged dependent variable on the right hand side?  Any ideas what 
might be going on?
