One approach in Stata8 is:
foreach j of numlist 1/18 {
if `j' < 10 {
local var b0_0`j'
}
else {
local var b0_`j'
}
... do something with `var' here ...
}

Subject: st: subscripts for loop?
> I'm stumped on a programming problem. I need to refer to a sequence of

> then j = j+1, etc., referring to b0_j. But this won't work. My boyfriend
