The Scripting Style Guide was recently updated to include this note about nesting conditional expressions:
When nesting conditions I've found it helpful to use a separate line for each condition, making use of the "\" line continuation character and putting the conjunction in all-caps to draw attention to it:
if (tWd is among the lines of the windows) \
AND (the vis of stack tWd is true) \
AND (the mode of stack tWd = 1) then
...
end if
This means a few extra characters when you're typing, but the clarity is well worth the effort. Conditional expressions are the heart of complexity, and the more complex your code is the more difficult it can be to maintain and enhance. Giving them a little extra attention when you write you code can pay big dividends down the road if something breaks.
