It will be a block of 400 bytes, but each 4-byte block is going to
be expected to be in the VAR format when looked at from the skills angle,
and will be expected to be INT or FLOAT format when looked at from the struct side.
By 'type' format I mean which of the 4 bytes is the Most-Signifigant byte,
which is the least, which is a multiplier and that sort of thing.

Its not a lite-c thing, its a true C thing. Try looking around some C or C++
tutorial sites and you may find how INTs and FLOATs are internally structured,
but you'll need to ask the Devs about how the VAR is structured.
