ive been wondering why wont codes make a file
.model small
.stack 100h
.data
buffer db 10,?, 10 dup(' ')
.code
start:
mov ah,1
int 21h
cmp al,"1"
je input
jne finish
input: ; will input string i.e "qw.txt"
mov ax,seg buffer
mov ds,ax
mov dx, offset buffer
mov ah, 0ah
int 21h
push ax
jmp print
print:
xor bx, bx
mov bl, buffer[1]
mov buffer[bx+2], '$'
mov dx, offset buffer + 2
mov ah, 9
int 21h
creatfile: ;creating a file like *txt
mov ah,3ch
mov cx,0
pop bx
mov ah,3ch
int 21h
finish: ;terminate program
mov ah,4ch
int 21h
end start
the code above doesnt work,doesnt create file qwe.txt when executed btw i place cmp so that when i press 1 it goes to createfile and jne to terminate program..
but the code below works and is the opposite of jump statements above how come it works but the logic is same right?
