Any algorithm or advice for removing extra white space would be appreciated.



trim:

push es
push ax
push bx
push cx
push si
push di



    mov di,si

    mov bx,si

    mov ax,[bp+4];;; taking message of string from stack//

    xor cx,cx


copyloop:
lodsb
cmp al,' ';;space ascii
jne spaces



    dec cx

    stosb

    jmp copyloop



    ;;;;; copy next to previous index





    ;if equal to Null termination  

    cmp al,0

    je store


spaces:
mov cx,1

mov bx,di
jmp copyloop



store:

mov [bp+4],bx



    pop di
