assume cs:code,ds:data,ss:stack
stack segment
stack ends
data segment
mess1 db 'this is a message ...',0ah,0dh, '$'
mess2 db 'this is another message ...',0ah,0dh,'$'
data ends
code segment
start:
mov ax,data
mov ds,ax
lea dx,mess1
call show_message
lea dx,mess2
call show_message
sh_me mess1
sh_me mess2
mov ah,0ah
int 21h
mov ax,4c00h
int 21h
show_message proc
mov ah,09h
int 21h
ret
show_message endp
sh_me macro str
local isdecm
lea dx, str
mov ah,09h
int 21h
endm
