Is it possible to get an individual element of an array?

Question

assembler

The fact is that when I try to get a single element, I get all the elements of the array starting from [N], because there is no sign $
stringT is a string that stores the entered numbers from the keyboard
at 123

mov  dx, offset StringT[1]
    mov   ah,9
    int   21h

23 will be displayed instead of 2.
I thought maybe you can add an array element '$', but did not find how to do it.

Answer 1

If you need to display a character:
