+In 64-bit editions some interpreter internal variables are moved or absent, notably !336 (pointer to temporary buffer), !368 (temporary storage for ON ERROR LOCAL), !424 (pointer to *KEY storage), !432 (pointer to event queue) and !440 (pointer to user-defined characters). These make way for 64-bit pointers ]332 (pointer to string accumulator), ]364 (pointer to error string), ]420 (pointer to path/filename buffer), ]428 (pointer to keyboard queue) and ]436 (pointer to current *KEY expansion).
