Using &LABEL

	"I could imagine horrible things like passing the address of a
	label to another function and executing a goto."

>From K&R:

	"Control may be transferred unconditionally by means of the

		goto identifier;

	The identifier must be a label located in the current function."

Thus, no "goto parameter".

Back in my youth, I remember wading through a good deal of v6 code
which used "signal(2,&label)" to transfer control within the procedure
on receipt of control-C.  This sort of thing seems to have died out.
