    TASM/turbo assambly

    I had to write program which finds all negative elements in columns and calculates their average values and i had to do this with index addressing method. My code below:
    Code:
    .model tiny
    .code
    .startup
               Org 100h
               Jmp Short Start
    Vector     Dw  2, -7, -1, 16, -15
    N          Equ 5
    
    
    Start:
     
               Xor Bx, Bx
               Xor Dx, Dx
               Xor Si, Si
               Mov Cx, N
               Dec Cx
    S:
               Mov Ax, Vector[Bx]   
               Add Bx, 2
               Cmp Ax, 0
               Jge _next
               Inc Si
               Add Dx, Ax
               
    _next:     
               Dec Cx
               Loop S
    
    
    AVG:
               Mov Ax, Dx
               Cwd
               Idiv Si
    Could someone help me fix my errors? I would be very thankful.

    Not to hijack the thread, but TASM is very outdated...might want to learn The Netwide Assembler: NASM instead. It's cross-platform and will write 16, 32, and 64 bit programs.

    What the heck is with these two lines:

    Code:
    Cmp Ax, 0
    Jge _next
    You're skipping all non-negative values? Why is this comparison even here?
    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}
