I have an list variable mixed with strings and real numbers
i.e. ("A" "B" 2.0 3.4 ...)
Now i want to store this list in an enviroment system varibles using
(setenv ...)
However, it can only store a string not a list...
if I transfer it into a string, it might be hard to extract the data when i need it...
Anybody get a better way to do this, please give me a hand.

MAYBE....

指令: (SETENV "LAI" "(\"A\" \"B\" 2.0 3.4)" )
"(\"A\" \"B\" 2.0 3.4)"

指令: (READ(GETENV "LAI"))
("A" "B" 2.0 3.4)

指令: (TYPE(READ(GETENV "LAI")))
LIST

use your method,it's not hard.

use (vl-prin1-to-string...) transfer it to string, when you extract,after you extract a string "str",you can use (read str),you will get a list.
