The word : is the most used creation word in FORTH.
Subsequent execution of NOM performs the execution sequence words compiled in his "colon" definition.
After : NOM, the interpreter enters compile mode. All non-immediate words are compiled in the definition, the numbers are compiled in literal form. Only immediate words or placed in square brackets (words [ and ]) are executed during compilation to help control it.
A "colon" definition remains invalid, ie not inscribed in the current vocabulary, as long as the interpreter did not execute ; (semi-colon).
Example:
: NAME nomex1 nomex2 ... nomexn ;
NAME \ execute NAME
