Have you looked at UML, This may be an oblique
answer but 'activity' diagrams will help
The UML Tool i'm using is minUML (from www.minuml.com ) is pure Delphi (and will
have Delphi Web Script scripting)
If you are getting repeated calls in the else
then your process flows are wrong (making decision a ahead of b or not
combining
your decisions logic correctly, UML activity diagrams are like flowcharts but have 'forks'
and 'joins' which help in modeling this
example
if you have 2 binary forks (hard to express in
text) but you have 4 outcomes (but only 3 decisions), coded in if then
else you get (pseudo code)
if conda
then
if condb then proc1()
else proc2()
else
if condb then
proc3()
else proc1()
you are using 2 binary decisions to get 3
outcomes, A solution I saw once from the Mark Edington? (borlands
ADOExpress architech)
for this was (and I would never thought of it)
pls excuse any syntax errors
const
Decision: array[boolean,boolean] of Int =
((1,2),(3,1));
case Decision[conda,condb] of
1: proc1()
end

Help!
I'm building myself an increasingly complex
maze.
Has anyone any tips on how "real programmers" keep track
of the logic that is necessary to ensure that multi level nested
if...then...else statements are constucted properly.
I seem to be often getting into situations where I find
myself executing similar sets of statements after 'else's at different
levels in a set of nested if...then...else's.
Are there any *methods* that one can employ to ensure that
these structures are correct?
I find that after about 2 levels I cannot comprehend what
else is going to be executed when.
Any tips or references would be greatly
appreciated.
TIA
Mark
