ERASE	This may seem a silly function - when called it returns all
its arguments except for the last!  For example:
 	: ERASE(1,2,3) =>
 	** 1 2
.br
However, it is often useful  if you want to use only one of
the results of a function which produces two results.
 	: ERASE(3) =>
 	**
 	: ERASE(1,3) =>
 	** 1
 	: ERASE(10//3) =>
 	** 1
 	: FUNCTION ISMULTIPLE(X,Y);
 	:	ERASE(X//Y) = 0
 	: END
.br
How does ISMULTIPLE work? (What does it do?)
