\\ *** Loadscreen f<>r Arbeitssystem *** 03oct86we
|

|
|
|
|||
|
|
Die folgenden Screens werden benutzt, um von FORTHKER.PRG aus
|
|||
|
|
ein Arbeitssystem hochzuziehen.
|
|||
|
|
|
|||
|
|
Da der Kernal noch kein Filesystem enth<EFBFBD>lt, mu<EFBFBD> dieses zun<EFBFBD>chst
|
|||
|
|
im Direktzugriff geladen werden. Assembler und Fileinterface
|
|||
|
|
m<EFBFBD>ssen daher unbedingt am Anfang auf der Diskette liegen, damit
|
|||
|
|
die absoluten Blocknummern stimmen ($16 und $18).
|
|||
|
|
|
|||
|
|
Anschlie<EFBFBD>end werden die Files FORTH_83.SCR und FILEINT.SCR er-
|
|||
|
|
zeugt und die View-Felder der Worte auf diese Files gepatched.
|
|||
|
|
Dazu m<EFBFBD>ssen diese Files auf Diskette vorhanden sein.
|
|||
|
|
|
|||
|
|
Schlie<EFBFBD>lich werden mit INCLUDE die Files geladen, die man in
|
|||
|
|
seinem System haben m<EFBFBD>chte.
