Here I can quote Fred Brooks in "The Mythical Manmonth"
(Anniversary Edition, A-W 1995), on page 102
'Representation Is The Essence of Programming':
"...This is where the heart of a program lies.
Show me your flowcharts and conceal your tables,
and I shall continue to be mystified. Show me your
tables, and I won't usually need your flowcharts;
they'll be obvious."
