There might be some typos in the previous code I said it worked.
I would like to assure you that the = is required and it works:
. forval i=1/`=ng' {
2. mat p=inv((r1+vu)/ns[`i'])*r1
3. mat q=r2*(idd-p)
4. mat xtilde`i' = xmean*p +mux3*(idd-p)+dz*q
5. }
Thanks to everybody and happy new year,
Nicola
