Im volksFORTH rev.3.81.41 treten, bedingt durch die Vielfalt an
|
||||
Grafik-Karten f<>r den PC, unter Umst„nden Probleme mit dem CURSOR
|
||||
auf. Denn in dem meisten PCs verrichtet eine Hercules-Karte ihre
|
||||
Dienste, auf die einige Worte im EDITOR und im Kommando-zeilen-
|
||||
Editor CED zugeschnitten sind.
|
||||
Die Worte CURON und CUROFF bestimmen das Erscheinungsbild des
|
||||
Cursors durch Zahlenwerte f<>r CURSHAPE, die grafikkartenabh„ngig
|
||||
sind. Hier bietet sich eine Žnderung mit Hilfe des Video-
|
||||
Interrupts INT$10 an, dessen Funktion $3 im C-Register die
|
||||
aktuelle Start- und End-Zeile des Cursors wiedergibt. Als
|
||||
Warnung: Im Zuge meiner amateurhaften Versuche zur
|
||||
Interruptprogrammierung hat, nach ungesichertem R-Register, ein V
|
||||
(aktuellen Screen editieren) daf<61>r gesorgt, daá meine gesamte
|
||||
freie Festplattenkapazit„t der Datei EDITOR.SCR zugeschlagen
|
||||
wurde.
|
||||
Mit den neuen Varianten von CURON/OFF m<>áten auch EGA und andere
|
||||
Karten einen Cursor auf dem Schirm anzeigen. Mit dem
|
||||
Kommandozeilen-Editor CED h„ngt auch das zweite Problem zusammen:
|
||||
Wie man in SHOWCUR sieht, wird der Einf<6E>ge- oder šberschreibmodus
|
||||
durch das Erscheinungsbild des Cursors verdeutlicht. Da liegt es
|
||||
auf der Hand, daá in (EXPECT die Wortfolge KEY DECODE SHOWCUR
|
||||
nach jeder Zeicheneingabe das Aussehen des Cursor in Abh„ngigkeit
|
||||
vom jeweiligen Modus festlegt und ein etwaiges ( top bot) CURSHAPE
|
||||
unwirksam machen. Soll dem nicht so sein, k”nnte man eventuell
|
||||
die jetzt gel”schte Cursor-Anfangszeile in einem der beiden Modi
|
||||
INS/OVER beibehalten.

Das Problem für einige GrafikKarten, keinen Cursor zu haben,
|
||||
wird im CED.scr verursacht, denn SHOWCUR macht ein konstantes,
|
||||
GrafikKarten-abhängiges CURSHAPE.
|
||||
|
||||
Ein zweites Problem ist das sinnlose Arbeiten des Wortes
|
||||
CURSHAPE selbst: Die Cursorgröße wird neu eingestellt, dann aber
|
||||
von einem der Ausgabeworte (welchem?) gelöscht.
