Joseph,
thank you very much for your help and I solved my problem by the method you suggested.
By the way, is it a general way to deal with eliminating double quotes surrounding letters?
Namely, is there a function applied in this situation? I tried -real()- function, however, I got a missing value.
Thank you for any help.
Best regards,
Rose.

I have a localname xy containing some letters among which there is space.
And I want rename a variable the localname xy. Due to the space, I took the
-subinstr- funtion to eliminate the space. However, that treatment produced
double-quotes surrounding the letters. How to deal with it?
To make what I said clear, I take an example below.
local xy "ab cd ef"
rename variable subinstr("`xy'"," ","",.)
Based on the typing above, Stata gives an error message "( not allowed r(101)".

Use `=. . .' to evaluate the function. See example below for details.
