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
stosb
mov bx,di
jmp copyloop



store:

mov [bp+4],bx



    pop di
pop si
pop cx
pop.......0 bx
pop ax
pop es
ret
