Displaying a String

Displaying a String

Displaying a String

(OP)
Hi all,
I want to display my string at a certain position on the screen. But with my coding, it displays weird ASCII characters at position 0,0 instead of "Please Enter Input...etc." onto the screen. Please help.

.data
MESSAGE1 DB "Please Enter Input Filename: ", 0

.code
        org 100h


        MOV AX, 0B800h
        MOV ES, AX
        MOV AH, 07h
        MOV DI, 0
        MOV BX, 0
        MOV CX, 29

DISPLAY:
        MOV AL, MESSAGE1[BX]
        MOV ES:[DI], AX
        JZ THEEND
        INC BX
        ADD DI, 2
        LOOP DISPLAY

THEEND:
        INT 20h

RE: Displaying a String

Hello,

you are writing a DOS .COM file but those only consist of one segment. Move the data in the data segment below the last code, and remove the .data, and everything works fine.
