Binyamin Dissen has already made the crucial point: LINK[X] specifies a name
(or alias); SYNCH[X] specifies an address.
An apparently not quite obvious corollary of this distinction is that LINK[X]
makes a LOAD[X] available under the hood/bonnet; SYNCH[X] does not. The exit
routine nominated in a SYNCH[X] macro instruction must already be present in
virtual storage. The load module or program object nominated in a LINK[X]
macro instruction need not be. (A copy known to be present will, of course, be
used if it is refreshable or reentrant.)
