This example from the help file works, even though it does not make too much

use "Italy-OutlineData.dta", clear

label(data("Italy-RegionsData.dta") select(keep if id<3 & id>1)

I am trying to use "keep if" to trim down the data that I want to use to
label some observations on a plot.

Using "keep if" in the following command line seems to work:

spmap using "uscounty.dta" if state=="42", id(_ID) cln(2) ocolor(gs12 gs12)
fcolor(white white) legend(off) label(data ("coord.dta") select(keep if
batch <3) y(lati) x(longi)
label(batch) ) title("Big Foot Sightings in Pennsylvania")

BUT, if I try to do the following:
...label(data ("coord.dta") select(keep if batch >3 & batch<6) y(lati)

I get an "invalid syntax" error...

How can I use the keep command with 2 conditioning statements?

Any suggestions are appreciated.
