How to extract one string from a local

[Wendao Xue]

Hi, I'm wondering if I can extract one string form a local, for example
local a `" "AMI" "CFAS" "CFASRA" "'
di a[2] will give me CFAS

Thanks!

di a[2] will give me CFAS

No, it will give you a syntax error, unless you also have a variable named a, in which case it will give you what ever is sin the second observation for that variable. To extract the second "word" from a local macro it would be:

local a `" "AMI" "CFAS" "CFASRA" "'
display `"`:word 2 of `a''"'
