Oops! Sorry . My previous message was filled by the sdm command.
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
