Yeah...
Didn't Fred Brooks in "The Mythical Man Month" complain that OS/360
wasted 24 bytes by catering for a leap year changing from 28th Feb to
29th? The operator could manually fix that without OS help - after all,
it only happened once every four years.
So, you are updating your master file with millions of records and for
each record you go through 5 excess instructions (say) to cater for the
year 2100. How long extra will several lots of 5 million instructions
take on today's BIPS engines? Less than a thousand I/O operations?
It's nice to reduce path length overhead, but it's also nice to be
future proof - or at least future tolerant.
Cheers,
Greg
