Is there a pattern for executing instructions from a file?

Question

Design patterns

For the second week I have been looking for a solution for reading the script and its subsequent execution.
The bot will read the script and perform actions according to the instructions.

I sketched a diagram, how I imagine it.


Well, something like this.

function process () {
  state = bot[action](arguments)
}

Plz drop an idea.
Where to peek?
