generate bin_number = ""
local u 10
forvalues i = 900(`u')1500 {
local I = `i' + `u'
replace bin_number = "`i'-`I'" if condition > `i' & condition <= `I'
}
It could be done with one fewer line, the price being a veritable
snowstorm of quotation marks:
generate bin_number = ""
local u 10
forvalues i = 900(`u')1500 {
replace bin_number = "`i'-`=`i' + `u'')" if (condition > `i' &
condition <= `i' + `u')
}
