Thanks.

At 09:47 AM 6/28/2004, you wrote:
I think what you are seeing is intended behavior and I would guess that your
foreach loop has 242 lines.  Stata's output for loops shows each line of the
loop once (numbered) and then shows all of the output without showing you
the commands for that iteration of the loop.

I usually include lines in the loop to display relevant information about
what each result refers to or else I re-write the inside of the loop as an
ado file that produces labeled output I want and then just call the ado file
inside the loop.

Thanks, that's what I ended up doing.


For your example,

program define myprog
syntax using/
use `using', replace
....
noi di "Regression of ......using `using'"
...
end

foreach name in solpro1 solpro2 solpro3 solpro4 solpro5 {
myprog using `name'
}
