Re: st: Double loops

[Nick Winter <nw53@cornell.edu>]

I believe that there were conditions under hwich Stata 7 would crash, when 
there was code following on the same line after an open brace ( "{" 
).  THis is why, I think, Stata 8 does not allow that usage.

So you might try something like this:

foreach nvar of varlist var1 var2 var3 var4 {
   foreach X of varlist var5 var6 {
     quietly tab `nvar' `X', all
     if r(p)<0.05 {
        display "Significant at the 5% level: `nvar' `X' p=" r(p) " / " 
r(p_lr)
     }
   }
}
