no room to add more variables
    An attempt was made to add a variable that would
have resulted in more than 2048 or 2047 variables
    (Stata reserves one variable for its own use). 
You have the following alternatives:
 
     1.  Drop some variables; see help drop.
 
     2.  If you are using Stata/SE, increase maxvar;
see help maxvar.
r(900);

   describe , short
 
Guessing: If you used -xi:- when running the regression 
analysis, you created new variables, and that may 
explain your problem.
