I want to print this array but also highlight specific characters from said array. This is my code:

As you can see, the array 'indx' have the positions of the chars (The first number is the effective lenght of said array) that I want to highlight so I check if bx is in the position of said character to print it highlighted. I have two problems at the moment, the first one is the highlighted characters are printing in a kinda random position and that messes up the rest, but I think I know why the position of the highlighted character that prints is wrong, because the interrupt that I use uses dh and dl as positioners but I do not know how to make it so it continues the flow of the rest. The second problem is that the character that prints is wrong, if you run it and check the variable char, it has an 'Z' but it prints a 'T'. I really need help. Pretty please. :(
indx db 5,11,26,41,45 dup (' ')
It could be that this line is not what you think it is!
Reading your explanation I think you really meant:
indx db 5, 11, 26, 41, 45, ' '
That is the length of the array which is 5, then followed by 4 offsets to the highlighted characters and 1 space character as a list terminator.
the first one is the highlighted characters are printing in a kinda random position and that messes up the rest, but I think I know why the position of the highlighted character that prints is wrong, because the interrupt that I use uses dh and dl as positioners but I do not know how to make it so it continues the flow of the rest.
Because your code to output the highlighted character uses mov dx,0000h, the BIOS function 13h places the character in the upperleft corner of the screen and the other, 'normal' characters will continue from there.
All you have to do is to ask BIOS where the cursor is at that moment using function 03h:
Replace
mov cx, 1; calculate message size.
mov dx,0000h
mov ah, 13h
int 10h
by
mov ah, 03h ; BIOS.GetCursorAndConfiguration
int 10h ; -> CX DX
mov cx, 1 ; message size
mov ah, 13h ; BIOS.WriteString
int 10h
Function 13h fetches from ES:BP. Did you setup the ES segment register?
The second problem is that the character that prints is wrong, if you run it and check the variable char, it has an 'Z' but it prints a 'T'.
Probably resolving the first problem will also resolve the second one.
printSpecial:
push ax
push bx
push cx
mov cx, 1 ; ReplicationCount
mov bx, 00F0h ; DisplayPage 0, Attribute BlackOnBrightWhite (11110000b)
mov al, dl ; Character
mov ah, 09h ; BIOS.WriteCharacterAndAttribute
int 10h
mov ah, 0Eh ; BIOS.TeletypeCharacter
int 10h
pop cx
pop bx
pop ax
...
Function 09h will write your character with the colors that you need, and then function 0Eh will advance the cursor normally.
