help with EMU8086

I need help figuring out how to get this program to display a vertical line is displayed from coordinates (50, 50) - (50, 75) in addition to the horizontal line currently displayed by the program.

I am using the program EMU 8086
I need to know how to do it within the next 2 hours, can anybody help me?

name "mycode"   ; output file name (max 8 chars for DOS compatibility)

org  100h    ; set location counter to 100h

; you may customize this and other start-up templates
; the location of this template is c:\emu8086\inc\0_com_template.txt

; disable blinking (for DOS/BIOS compatibility).
mov ax, 1003h 
mov bx, 0       
int 10h

; this is just a random code
mov ax, 1234h      ; load ax with hexadecimal value.
mov dx, 0x1234     ; 0x is a valid hexadecimal prefix too.
mov ax, 1234       ; load ax with 04D2h = decimal 1234 = 10011010010b.
mov ax, 0ABCDh     ; must have 0 prefix if first digit is A,B,C,D,E or F
mov dx, 0xABCD     ;                                      or use 0x prefix.
mov dl, TeSt1      ; the integrated 8086 assembler is not case sensitive, test1=TeSt1, AX=ax, etc...
jmp n              ; jump over 1 byte to skip over the test1 variable.
test1 db 20h       ; 1 byte variable 20h = 32.

add dl, dl         ; dl = dl+dl = 20h+20h = 40h = 64 = 01000000b
inc dl             ; dl = dl+1 = 41h = 65 = 'A' (ascii code)
mov ah, 2          ; ah and dl are parameters for int 21h
int 21h            ; print 'A'.
mov dl, 1          ; ascii code 1 is a funny face.
int 21h            ; print it.
mov al, 11100101b  ; b suffix is for binary. 11100101b = 0xE5 = 229

CHEER UP EMU KID

I am now at the bottom of /prog/ front page, and there's not
one meaningful thing so far. It's all unfunny retards typing the same crap unfunny retards have been typing for 6 years.
See you in a month, retards.

if you dont like it, go away.
nobody cares.

You have to mess around with the loopstart to get the verticle to be displayed.
