In addition to performing the requested action, each command entered into 22Lookup causes an entry to be made in the "sessions file" thereby creating a historical record of user interaction with the app. One reason for this command implementation is to facilitate support. Alternatively, it is sometimes the case that one might recall that they obtained useful information from 22Lookup but somehow the exact command was forgotten. Using the sessions command will allow the user to scroll through previously entered commands to hone in on the command of interest.
