If you instate the following options at the beginning of your script you will see what they mean real quick

Code:

$RC = Setoption(NoVarsInStrings,ON)
$RC = Setoption(NoMacrosInStrings,ON)
$RC = Setoption(Explicit,ON)


Another really good one is

Code:
If not @logonmode
 Break ON
EndIf


With the first section your script will start screaming (beeping everytime you execute it) until you fix it to comply with all the SetOptions.

Can be frustrating at times, but it does make one a much better coder.
