\ CP/M 2.2 File-Interface (3.80a) UH 05Oct87 Dieses File enthaelt das File-Interface von volksFORTH zu CP/M. Damit ist Zugriff auf normale CP/M-Files moeglich. Wenn ein File mit USE benutzt wird, beziehen sich alle Worte, die mit dem Massenspeicher arbeiten, auf dieses File. Benutzung: USE <name> \ benutze ein schon existierendes File FILE <name> \ erzeuge ein Forthfile mit dem Namen <name>. MAKE <name> \ Erzeuge ein File mit <name> und ordne \ es dem aktuellen Forthfile zu. MAKEFILE <name> \ Erzeuge ein File mit CP/M und FORTH-Namen <name>. INCLUDE <name> \ Lade File mit Forthnamen <name> ab Screen 1 DOS RESET \ zum Wechsel von Disketten. (Oh!
