LIST

This will list the contents of the screen number held on the top of the stack.

e.g.      6 LIST

will list screen 6 to the screen. Note that if source has not been typed into any of the screens, they will probably contain garbage .

FORGET

This is used to delete part of the Lightning dictionary. Please note that not only will the word following FORGET be erased, but so will every word defined after it.

e.g.            FORGET EXAMPLE 

will delete the word EXAMPLE (if it exists) along with any other word defined after it. 

VLIST

This is just typed in as a single word with no parameters. It will cause a list of all the words defined so far; pressing BREAK will stop the listing. 

LOAD

This will compile the source code that you have created using the editor into the dictionary, to became new word. Loading will terminate at the end of a screen or at the Forth word ;S unless the “continue loading” word --> is used at the end of a screen. The idea of the screen will become obvious in the next section on editing.
