hello im trying to print a letter out three times after i capture it. i am using the display interumption

.model small
.stack 10h
.data
.code

mov ah, 01h; captura una tecla
int 21h; int=interupcion 21=sistema operativo D.O.S captura en AL


; imprimirla
mov dl,al
mov ah,02h

mov dl,al
mov ah,02h

mov dl,al
mov ah,02h
int 21h

mov ah,4ch
int 21h

end


i couldnt find an interruption to display something more than once but i figured assembly could be similar to a c# so i thought i would display three times and it would function, when i execute the program an error appears after i capture the letter i want to see. could someone help me out?

This works for me:

ORG 0x100 


mov ah, 01h; captura una tecla

int 21h; int=interupcion 21=sistema operativo D.O.S captura en AL



; imprimirla

mov dl,al

mov ah,02h

int 21h 


mov dl,al

mov ah,02h

int 21h 


mov dl,al

mov ah,02h

int 21h


mov ah,4ch

int 21h

The 'ORG 0x100' is NASM syntax, and I don't know if similar is needed for TASM, but the rest of the code can be applied to TASM.
