// used in many battle files, it seems as though Hisashi Sogabe wrote
// some sort of macro to replace the use of actually calling memset.
// Perhaps it was thought calling memset was much slower?

// The compiler wont allow us to locally declare ptr in this macro; some
// functions that invoke this macro will not match without this egregeous
// assumption about the variable names, so in order to avoid this assumption,
// we opt to pass the variables themselves, even though it is likely that
// Sogabe assumed the variables were named src and dest. Trust me: I tried to
// avoid assuming variable names, but the ROM just will not match without the
// assumptions. Therefore, these macros are bad practice, but I'm putting them
// here anyway.
