Code Your Own Forth - Set Rules on Word Declarations
In this video, we configure our Forth system to not allow user-defined words to be named integers. For example, a word cannot be named "19". This prevents an issue in which every time the user enters a certain number, a different number is added to the stack in its place. Adding this rule demonstrates how rules can be added to word declarations in general.
