This basically tests whether or not the variable MyStringList is nil or not.
It is also a good idea to adopt use of the FreeAndNil procedure which, as the name suggests, sets object references to nil as well as freeing the object. Otherwise subsequent calls to Assigned will give you incorrect results.

Basic question. How do you test for the existence of a TStringList (for example) before reading from it - or do you just do a try...except?
