A system includes a first computer configured to store and run a computer program. The computer program includes an internal interface with tangible machine-readable instructions stored on the first computer, to provide communications between the computer program and external computers and our computer processes. The system also includes a command interpreter configured to interface with the computer program through the internal interface. The command interpreter includes tangible machine-readable instructions to detect a script file; generate one or more command objects, interpretable by the internal interface, representative of a functionality defined in the script file; generate a command script comprising the generated command objects; and execute the command script by executing at least a portion of the machine-readable instructions in the internal interface.
