Get Value of Barcode

I am trying to get the value of a barcode directly into a variable. I am not using a textbox, label or any control to hold the value, I need it in a variable so I can parse it.

The User has a list of Barcodes each acting as a specific command. Any of these Barcodes can be scanned at any time so I would like to be able to parse which command was scanned and execute the appropriate procedure. Ideally to me it sounds simple but I am just not too familiar with how the Barcode Scanner works.

I understand how to focus on a textbox and input value, but not to a variable.

Thanks

FYI: I am using a Wasp Barcode Scanner Model WLR8905
IF relevant.
