Hi
I wanted to change variable names through strings. Since I use the similar property while I read variable from .nc file. For instance,
a = "var"
b = addfile(filename + ".nc", "r")
c = b->$a$
In this case, I can change a to change the variable names.

Now I wanted to use the similar feature to modify variable names. For instance,
a is a string,
a = "var"
b is a variable. I want to modify b by using
b = $a + "a01"$
Unfortunately, I got the error below.

fatal:syntax error: line 1 before or near $
b = $
Do you know whether these is any way to change the variable name like what I want?
Thank you
Zhifeng
