st: how to solve numerical overflow

["Linda, X Zhu" <lx_zhu@hotmail.com>]

Dear all,
My dataset has more than 17000 observations with more than 100 variables. 
For my analysis I have to generate quite many variables  based on the 
initial variables for a Tanslog function with many interacted terms (56 
items). But when I run my model, I got the error message:  r(1400). I 
checked the stata help, it says:
       numerical overflow;
       You have attempted something that, in the midst of the necessary
       calculations, has resulted in something too large for Stata to
       deal with accurately.  Most commonly, this is an attempt to
       estimate a model (say with regress) with more than 2,147,483,647
       effective observations.  This effective number could be reached
       with far fewer observations if you were running a frequency-weighted
       model.

But it seems that there is no suggestion for solutions to this problem. How 
can I solve it?
Thank you!
Linda
