Note that ArrayName = nil destroys the arrayNAME '''not''' the array content.
Array content is 'destroyed' when no more ArrayName'''s''' refer to the content.

'''Never ever assign a value to ''nil''!'''
Doing so creates a global variable with the same name that overrides the "command" ''nil'':
  foo = "foo";
  nil = "bar";
  foo = nil;
  hint foo; // displays "bar"

While [[isNil]] isn't available in OFP/CWA you can easily emulate it with something like this:
