Is it possible to enforce the declaration of local variables?

Question

I have defined a local variable

 local tSuppressLines

I would like to make sure that local variables are checked so that if I have a typo like

   if  not tSuppessLines  then
      -- do something
   end if

I get a warning.

Yes, switch on "strict compilation mode" under "script editor" in preferences.

When in the script editor, there is also an item under the "Edit" menu, "Variable Checking", which toggles the same setting, but doesn't make the change persistent - on next launching the IDE, the value set in preferences will be restored.

This can be useful because sometimes you need to edit a script in which variables haven't been consistently declared (and literals haven't been quoted); and don't have time to make and test those changes. So you can temporarily toggle this checking off; and even if you forget to set it back, the corruption won't spread too far.

(This is an improvement on previous behaviour - before version 6, the menu item toggled the preference item, and vice versa)
