Newbie... Strict Compilation mode

[Bernard Devlin]

Another side-effect of explicit variables is that some code may well
behave differently.

Consider this:

 local tVar, tSQL
 if tVar is empty then ...

Since explict vars requires the declaration, it will affect the result
of the following conditional.  With the declaration then the condition
will be true; without the declration the condition will be false.
