Dear all,
I have one question about the use of local macros.
For example, assume the date

ID     ny_price
ny      5
wa      4

set obs 2
gen str ID=""
replace ID="ny" in 1
replace ID="wa" in 2
gen ny_price=4
replace ny_price=5 in 1

Then My question comes from the following differences:

. local city ny

. replace `city'_price=100 in 1
(1 real change made)


. local city ID[1]
. di `city'
. replace `city'_price=100 in 1
weights not allowed
