    The program is supposed to read numbers from a .txt file and write colors to the screen depending on which number is read. My problem is no numbers are being read from the file. Thank you very much for the time and help!
    Code: Cpp
    Code:
    INCLUDE Irvine16.inc
    
    .data
    buffer byte 0
    fileName byte "pix.txt",0
    fileHandle word ?
    y byte ?
    x byte ?
    
    
    .code
    main PROC
    
    mov ax,@data
    mov ds,ax
    
    mov ah,3dh		;opens the file to read
    mov al,0
    mov dx,offset fileName
    int 21h
    jc quit
    mov fileHandle,ax
    
    mov x,0
    mov y,0
    
    mov ah,3fh		;reads a single byte
    mov bx,fileHandle
    mov cx,1
    mov dx,offset buffer
    int 21h
    
    mov al,buffer
    
    begin:
    mov ah,02h
    mov bh,0
    mov dl,x
    mov dh,y
    int 10h
    
    mov ah,3fh		;reads a single byte
    mov bx,fileHandle
    mov cx,1
    mov dx,offset buffer
