start:

VIDEO_MODE:     .data.l (0x80000100)    ; data statement with hexadecimal operand
                                        ; ... and address of video mode setting.
VIDEO_ADDRESS:  .data.l (0x80000104)    ; address of video address pointer

VIDEO_MEMORY:                           ; this is the address we will store into VIDEO_ADDRESS

Oh, that's nice...

Welcome to the Blackvoxel Forum, Karats 

We see you managed to understand how the Assembly robot is working without example.

Guess you already have some good knowledge about hardware to have made this...

Yes, examples about programming assembly robot are missing. We'll publish some examples to help understanding.

We'll give you also some though on your program to help improve it.
