\\ *** Assembler *** 25may86we
|
||||
|
||||
Dieses File enthält den 68000-Assembler für volksFORTH-83.
|
||||
Der Assembler basiert auf dem von Michael Perry für F83 entwik-
|
||||
kelten, enthält aber einige zusätzliche Features.
|
||||
Wegen der Heap-Struktur im volksFORTH sind z.B. echte Labels
|
||||
verwendbar. Aus Geschwindigkeitsgründen enthält der Assembler
|
||||
kaum Fehlerüberprüfung, es empfiehlt sich daher, nach getaner
|
||||
Tat die Code-Worte mit einem Disassembler zu überprüfen.
|
||||
|
||||
Screen $11 enthält einen Loadscreen, mit dem man der kompletten
|
||||
Assembler auf den Heap laden kann, damit er während der Kompila-
|
||||
tionszeit zur Verfügung steht, aber keinen Platz im Dictionary
|
||||
verbraucht. Mit CLEAR oder SAVE wird der Assembler entfernt,
|
||||
wenn er nicht mehr benötigt wird.
