A typical
example form Graphs, Algorithms, and Optimization written by W.
L. Kocay & D.
L. Kreher give me a clue that
develop a new flow chart structure which do help on coding job, especially when
loop/decision are interwoven.
Please see Fig 1.

•First
I would make all branch on the right side.
•One
line command will only represent one process. Multi-line might count one
process if they are consecutive.
•When
we draw flow chart , every block will be on behalf of one process.
•Process
sequence will be top down. If possible ,don’t go up .

Fig 2, is a flow chart from a training book which teach
student how to get clear about flow chart operation. It fit beginners in the class
and too complicated and tedious to adopt
in real project. Afterwards, maintenance and revision are hard to follow up.
Fig 3 is my suggestion.
