As a user launching start the program I'm provided a command prompt where I can issue one of several commands, described below. After each command completes, the prompt returns, waiting for another instruction.

The program has a concept called the "queue". The queue holds the stored results from a previous search. As a user, I issue a search command to find records, then later issue another command to do something with those results. The queue is not cleared unless the user runs queue clear or a new find.
