While you can probably do this by brute force, with some logarithmic help
for calculating products, if I understand what you want to do, it is
simpler and quicker to exploit the iterative relationship between
successive observations:
gen newvar = var2 in 1
replace newvar = var2*(newvar[_n-1] + 1)
Hope this helps.
