I need some hyperAdvice:
	Is it possible to write an XCMD that remembers (internally)
data between invocations ? In other words, can I have states associated
with an XCMD so that the first call is treated differently from
subsequent calls ?
	A similer question: is it possible to have external global
data that is shared between separate XCMDs, or must I send such
info back to HC itself (and thus require the stack author to
create stack "global" variables.
	My preferred programming environment is LSC, but solutions
in any language would be appreciated. Thanks.
