Hi everyone, new here to the forum.

I recently picked up a TI-84+CE and am going through the bootcamp process of learning assembly programming.

I am trying to add two numbers together and display the output on screen. When I try to do this using the HL register I get a very inaccurate final value output to the display, here is what I am currently doing and what is not working.


Code:

#include "ti84pce.inc"
.assume ADL=1
.org userMem-2
.db tExtTok,tAsm84CeCmp
   call _homeup
   call _ClrScrnFull
   ld a,5
   add a,10
   ld h,0
   ld l,a
   call _DispHL
   call _GetKey
   call _ClrScrnFull
   res donePrgm,(iy+doneFlags)
   ret


I get as an output 13631503

I was wondering if I could get an explanation as to the internals behind how this value is being calculated.
On the ez80, hl is a 3 byte value, so the upper byte is non-zero.
Replace the line that sets h to 0 with ld hl,0

Thank you, that seems to have done it.
