assembly - Print item from char array? -

I have to print a letter like a letter such as this one:

  String DB 'ABC 0', '$'   
 I know I can print the whole string by doing this:  
  Lea DX, string mov , 0h I "21"   
 How can I just print a person's character like "A"?   
 
 
 you have 21 h / ah = 02 h  
  mov dl Byte PTR [String] mov ah, 02h int 21h   
  Byte PTR  means that you want, ok, a byte from the variable / pointer. To print the next letter, you increase the pointer:  
  inc string
