Hi.
I wondered if anyone had encountered the following error message & how 
they dealt with it:
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.
Each dataset is meta-analysed and the results are posted to a file. This 
file of results then contains 1000 observations and 24 variables.
