== Description ==
I created this function so I could define parameters on the command line to use in silent installs, the main push behind it was to define the default language that the installer should use. However, this should prove useful in any purpose where you need to retrieve a command line parameter.

See the syntax examples below; The stack will contain either the hard coded specified default value or the value supplied at the command line.
