st: Local Macros Containing Strings and Spaces

My question relates to strings in local macros with spaces. I'll
first relate what I am trying to do. I have a string variable that has
spaces in it. It looks something like this:
description
Organic Eggs
Nonfat Milk
Conventional Cherries
For each observation, I would like to generate a new variable,
grouping, based on the content of this description variable. I.e.
generate grouping = ""
replace grouping = "Poultry/Dairy" if (description == "Organic Eggs" |
description == "Nonfat Milk")
However, I have so many description values that I would rather do
something like:
local dairy "Organic Eggs" "Nonfat Milk"
local fruit "Conventional Cherries"
generate grouping == ""
forvalues i = 1/_N{
foreach v of local dairy{
replace grouping = "Dairy" if description == "`v'"
}
foreach m of local fruit{
replace grouping = "Fruit" if description == "`m'"
}
}
This does not work. In troubleshooting this problem, I noticed that
when I write the command: display "`poultry'", Stata returns Organic
EggsNonfat Milk. If I write the command: display `"`poultry'"' Stata
returns Organic Eggs" "Nonfat Milk. My question is, how do I address
strings with spaces in local macros?
Thank you in advance!
