Looks great! A couple of nitpicky little things (but then, I'm a
perfectionist). The VAT can never overflow pg. 7. In the variable routines
I've looked at, that causes a memory error. To get the variable size, don't
bother with _load_ram_ahl, just use _get_word_ahl ($521d) to get the size
in de. Also, if you want the variable size in bytes, there's a ROM routine
to do that. You know, because the size word at the start of the variable
isn't the size in bytes for a bunch of the variable types.
I call the routine _get_var_size. It's at $477f.
Input: a=type, bhl=var data ptr
Output: de=size (in bytes), ahl=var data ptr.
