I would like to write an assembly subroutine which can access globol
variables declared in C subroutine.  Ex:

/* This is a C subroutine */ long int L1, L2; C_sub() {
   extern int A_sub();
   L1 = 1;
   A_sub(L1, L2); }

* This is an Assembly subroutine
     module     A_sub
     entry.p A_sub * How to declared external L1 & L2 ???  * A_sub
     clr.l      d0
     cmp.l      L1,d0
     beq.s      done
     move.l #100,L2 done
     rts
     end        A_sub

Thank you for your help Minh Pham
