Asunto: st: while loop

I have a panel dataset with countries and years. I am trying to do some
regressions for every country in windows of 5 years. I want these 5
years to be overlapping so for example for United States, I want the
first regression to be for 1980-1984, the second 1981-1985, third
1982-1986 and goes on like this. I have used loop within a loop to do
this. As you can see from the do file below
local i=1

while `i'<131 {

local j=1980

while `j'< 2006 {

reg y  x1 x2 x3  if cc==`i' & (year==`j'|year ==`j'+1|year ==`j'+2|year
==`j'+3|year ==`j'+4)

local j= `j'+1


local i= `i'+1


However I have missing data for some countries and years, so when the
loop starts if it does not find any data for the first country and first
group of years the do file stops.
Could someone help me out here, how should I do these regressions.
I'd really appreciate any help .
