Question

So i have this:

I seached about something called utl_file package for exporting data from oracle database and so on, but i didn't understand much and didn't found what i was looking for. Basically what i want is, how can i "export" all of the output from the screen after running this useless package above? Is there a way to modify the package add features and stuff to it? It is possible? Thanks...
