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.
