	Think I've only seen CHAIN used in some BASICs to load another program
overtop the running one. Used it on my college data structures course --
assignment was a hashed-head multiple-linked list, and we were told we
could implement it in "any language <the instructor> understood" (he never
made that mistake again: he got BASIC, FORTRAN-IV, COBOL, and Sigma-6
assembly; only APL and SNOBOL weren't accepted). The BASIC only allowed for
4 open files in a program, and it was easier to invoke separate programs
for the phases of the assignment (a phone-book, hashed on names).

	I've only seen one other application using HHMLL -- and that was the
Amiga file system.
