|
||||
|
||||
Dieses File enth„lt den 68000-Assembler f<EFBFBD>r volksFORTH-83.
|
||||
Der Assembler basiert auf dem von Michael Perry f<EFBFBD>r F83 entwik-
|
||||
kelten, enth„lt aber einige zus„tzliche Features.
|
||||
Wegen der Heap-Struktur im volksFORTH sind z.B. echte Labels
|
||||
verwendbar. Aus Geschwindigkeitsgr<EFBFBD>nden enth„lt der Assembler
|
||||
kaum Fehler<EFBFBD>berpr<EFBFBD>fung, es empfiehlt sich daher, nach getaner
|
||||
Tat die Code-Worte mit einem Disassembler zu <EFBFBD>berpr<EFBFBD>fen.
|
||||
|
||||
Screen $11 enth„lt einen Loadscreen, mit dem man der kompletten
|
||||
Assembler auf den Heap laden kann, damit er w„hrend der Kompila-
|
||||
tionszeit zur Verf<EFBFBD>gung steht, aber keinen Platz im Dictionary
|
||||
verbraucht. Mit CLEAR oder SAVE wird der Assembler entfernt,
|
||||
wenn er nicht mehr ben”tigt wird.
