Query

Hi
 
 I am trying invoke Lisp Functions from C using foreign functions
interface. I 
Successfully executed the example given in the allegro CL directory
Examples/dll/ But When I am trying to assign values to a global variable
from
Lisp function or try to invoke another function not present in the Lisp
Based DLL
*.dxl. 
 Then a global variable value is not accessible from or it is not
invoking another function
 
Illustration:
 
 
(defun factorial (x)                                  ; assumes caller
will trap errors
  (block factorial
(fun x)  
(setf y 11)
            
            (return-from factorial 66)
  ))
 
Whenever factorial is invoked from C it assigns value for y but it seems
scope is limited to that function
As well as it does not invoke (fun x) which is not built in the same
image.
 
 
What I am looking for is a way to pass values from C to Lisp and store
them in a global variable.
 
Whether this can be achieved without storing them in the flat files etc.
 
 
Please let me know about the same.
 
Thanx in advance.
 
Regards
Amit
