This trick is not used just by novices, but also by professionals, to
protect from the sort of simple human errors to which every one of us is
prone. When you type If, type EndIf and maybe return, before filling
in the stuff between. In a complex nest of parentheses, type the
opening and closing parens and then back up and fill in the hole.
Makes the computer keep track of the pesky details so you can just get
done what you're there for. I don't always do the paren trick, but on
long lines I do. In fact, on really long ones, I'll put closing parens
on their own line sometimes. For example, I might type the following
two lines first:
sayMessage(OT_Message, formatString("
))
then come back and fill the whole thing in:
sayMessage(OT_Message, formatString("%1, row %2 of %3"
txt,
intToString(rowno),
intToString(rowCount)
))

I do somethin kinda weird, I guess, but it has really helped me a lot.
Immediately after a while statement, b4 putting any conditions, etc.,
I press enter twice, put my incrementor, then an endwhile. I always
also put an endif immediately after every if statement. I find it
eliminates a great many errors. I actually teach that in my scripting
course, because it's 1 of the tricks that's taken me awhile to figure
out (I'm not the sharpest tool in the shed), & I was hoping it'd help
my students not to have to go thru as many errors as I did b4 I
finally at least got a little smarter.
Hopefully some of yall on this list will find it helpful as well,
though I suspect most of u are a lot sharper than I & have probly
already figured it out.

Blame the computer--why not? It can't defend itself & occasionally
might even be the culprit
