I wish with a really sore heart that all applications and compiled programs do
those two tricks automagically and in a jiffy.
... like that windoze operating system which remembers your few last used
application programs and store it in the memory until the page file(s) gets
full... You run that application again, those associated programs are already
in the memory, no need to read in from your hard disk.
On the PCs, these languages, Clarion and Clipper, have background things which
dynamically optimize your memory and files in use while the MSDOS machines are
idle... Nice features which proved useful.
I believe on C64 from Commodore does the same thing, it does that infamous
garbage collection when your toy is idle...
So, something which is used to adjust your own performance while running, yes,
there is some overhead with those dynamic measurements, but if overall CPU
usage and I/O usage are fewer, that should be good.
I know about Linklist, COFVLFxx, XCF structures for RACF and such animals, but
they are somewhat static ('historical basis'), not dynamic like that SyncSort
Feature.

That is another feature I want to steal.... Sorry, but is it Friday today? ;-)
Thanks for your notes. Much appreciated.
