\\ *** VDI -Funktionen *** 12aug86we Dieses File enth„lt alle VDI-Funktionen. Zur genaueren Beschreibung verweisen wir auf die Dokumentation von Digital Research. Dieser Hinweis ist nicht zynisch gemeint, aber wir sind nicht in der Lage, das, was ATARI nicht zu leisten vermag, hier nachzuholen. Mit geeigneten Unterlagen (wo gibts die ??) sollte es aber m”glich sein, die Funktionen zu nutzen.

Zu Beginn eines Programms sollten ansonsten alle Device-Typen einmal mit sin_mode auf Sample geschaltet werden.
