Dear all,

The program Svend gave before is total right. I made quotas mistake
when I coded the loop.

In order to show my graditude and respect to Svend and Michael
Blasnik, I made a tiny change on the pragram and it is equivalent to
Svend's.

gen total=0
forvalues i=4 15: 386
local j=`i'+4
replace expens3=expens+var`i'*var`j'
}

Thanks a lot..
