Hi,
I am dealing with commodity-level price data. I have price data of around 800 commodities. Commodity variables are named according to their commodity codes. I want to label each variable. Data is given below.

111.5 114.5 114.9 117.8 112.9 107.8 119.1
end

I'm using the following code to label variables. It incorrectly labels all variables by the last item of the local variable. I guess we have to use another local inside the loop. Tried but not able to fix it.
Code:

local vars `""ALL COMMODITIES" "I    PRIMARY ARTICLES"    "(A)  FOOD ARTICLES" "a.  FOOD GRAINS(CEREALS+PULSES)" "a1. CEREALS" "Rice" "Wheat" "'

foreach x of varlist wpi_* {
foreach y of local vars{
label variable `x' "`y'"
}
}
Thank you in advance for your help.
