0 % VolksForth 8080 Assembler UH 03Jun86
1
2 Der 8080 Assembler wurde von John Cassady, in den Forth
3 Dimensions veroeffentlicht und von Mike Perry im F83
4 implementiert. Er unterstuetzt den gesamten 8080 Befehlsvorrat
5 und auch Befehle zur strukturierten Assemblerprogrammierung.
6 Um ein Wort in Assembler zu definieren wird das definierende
7 Wort Code benutzt, es kann, muss aber nicht mit end-code beendet
8 werden. Wie der Assembler arbeitet ist ein interessantes
9 Beispiel fuer die Maechtigkeit von Create does>.
10 Am Anfang werden die Befehle in Klassen eingeteilt und fuer
11 jede Klasse ein definierndes Wort definiert. Wenn der Mnemonic
12 des Befehls spaeter interpretiert wird, kompiliert er den
13 entsprechenden Opcode.

11 Es findet keine Absicherung der Kontrollstrukturen statt, sodass
12 sie auch beliebig missbraucht, werden koennen.
13 Das ist manchmal aus Geschwindigkeitsgruenden leider notwendig.

2 Dieses File enthaelt Befehle, die den Assembler vollstaendig in
3 den Heap laden, so dass er schliesslich mit clear wieder
4 vergessen werden kann.
5
6 Dadurch ist es nicht notwendig in einer Anwendung den ganzen
7 Assembler im Speicher lassen zu muessen, nur weil einige
8 primitive Worte in Assembler geschrieben sind.

2 Ein Algorithmus, der die Dictionarysuche beschleunigt:
3 Zuerst wird uebr das gesucht Wort gehasht und in in einer
4 Tabelle nachgesehen. Schlaegt der Versuch fehl, wird ganz normal
5 gesucht. Suchzeit geht auf ca. 70-80% gegenueber normalem Suchen
6 herunter.
7
8 Hinzu kommen die Worte:
9 cash, hash-thread, erase-cash, 'cash, und found?
10
11 Im Kernal neudefiniert oder gepatched werden muessen:
12 (find, hide, reveal, forget-words
13
14 (find und (forget benutzen jejweils die alten Worte. Sie muessen
15 umbenannt oder in die neuen Worte eingebettet werden.

2 Dieses File enthaelt einen Decompiler, der bereits kompilierte
3 Worte wieder in Sourcetextform bringt.
4 Strukturierte Worte wie IF THEN ELSE, BEGIN WHILE REPEAT UNTIL
5 und DO LOOP +LOOP werden in einem an AI-grenzenden Vorgang
6 erkannt und umgeformt.
7 Ein Decompiler kann aber keine (Stack-) Kommentare wieder
8 herzaubern, die Benutzung der Screens und dann view, wird
9 daher staerkstens empfohlen.
10
11 Denn: Es ist immernoch ein Fehler drin!
12 Und um den zu korrigieren, ist der Sourcetext dem Objektkode
13 doch vorzuziehen.

3 trotzdem wuenschenswert eine Art File-Struktur zu besitzen.
4 Dieses File enthaelt eine einfache Implementation eines
5 Filesystems. Der/die Programmierer/in muss selbst die Direktory
6 auf dem laufenden halten: in ihr sind die Start-Bloecke des
7 entsprechenden Diskettenteils gespeichert.
8 Sogar eine Hierarchie von Direktories laesst sich so relisieren.

10 Vorgestellt wurde dieses FileSystem von Georg Rehfeld und auch
11 von ihm fuer volksFORTH implementiert (ultraFORTH auf dem C64).

1 Dieses File enthaelt die wichtigsten Werkzeuge zur Programm-
2 entwicklung: - den einfachen Decompiler
3 - der DUMP-Befehl
4 - den Tracer
5
6 Der einfache Decompiler wird benutzt, um neue Defining-Words
7 zu ueberpruefen. Der automatische Decompiler kann ja dafuer
8 nicht benutzt werden, da ihm diese Strukturen unbekannt sind.
9 (Benutzung: addr und dann, je nach Art: S N D L C oder B)
10
11 DUMP wird zum Ausgeben von Hexdumps benutzt. (from count DUMP)
12
13 Der Tracer erlaubt Einzelschrittausfuehrung von Worten.
14 Er ist unentbehrliches Hilfsmittel bei der Fehlersuche.
15 (Benutzung: DEBUG <name> und END-TRACE)
