The names of the machine's primitive data types are interesting, and refreshing if you're tired of the more well-known ones. These are the load instructions, for reading data from memory:

    Load a Byte           LDB $X,$Y,$Z
    Load a Wyde (2Byte)   LDW $X,$Y,$Z
    Load a Tetra (4Byte)  LDT $X,$Y,$Z
    Load an Octa (8Byte)  LDO $X,$Y,$Z

I thought the "wyde" in the instruction set reference was a typo, until I saw that it was used all over the place. :)

I guess it's better (less ambiguous) than "word", "long", "double word", and so on.
