When slTest is a local variable, you should initialize it to Nil.
Just to be clear
Initialize it in code not in the declaration, since in the declaration afaik
that makes it a static variable instead of a truely local one, even when
declared
with local scope.
You can only initialize a global variable. For "initialized local
variables" you need to use writable "constants" ;)
