Let me add a couple of details.
First, you need to watch lines like
. forv i=1/9 { graph x`i' y, by(z) saving(gx`i',replace) }
-- adding the "}" omitted by accident --
in which Stata is presented with everything on one
line. This is not _guaranteed_ to work. If the whole
is relatively simple, it will; but not otherwise.
However, that's circular, as "relatively simple"
is defined by it working.
The syntax you should follow with -forvalues-
or -foreach- puts each command within the loop
on a separate line, namely
. forv i=1/9 {
. graph x`i' y, by(z) saving(gx`i',replace)
. }
In practice, you can often put the last
brace } on the same line as the command before
it, as in
. graph x`i' y, by(z) saving(gx`i',replace) }
I don't think I've seen Stata complain at
that, although that's Stata's indulgence
rather than recommended syntax.
Second, and more positively, I often loop
something like this
forval i = 1/9
graph <whatever> if something == `i', t1(`i') saving(g`i')
more
}
The two extra details are the -more-, which ensures
a slide show not a movie, and a title which
shows which group you are seeing.
