||
Die Routinen in dieser Library entsprechen dem, was auch dem
|
||
Pascal-, C- oder Modula-Programmierer zur Verf<EFBFBD>gung steht.
|
||
F<EFBFBD>r eine genaue Beschreibung der einzelnen Routinen verweisen
|
||
wir auf die GEM-Dokumentation des ST-Entwicklungspaketes bzw.
|
||
entsprechende Literatur.
|
||
|
||
Aus diesem Grunde wurden die - teilweise kryptischen - Namen
|
||
von Digital Research beibehalten; auch die šbergabeparameter
|
||
der einzelnen Funktionen sind unver„ndert geblieben.
|
||
Der Aufbau einer FORTH-Library mit 'Super-Befehlen' ist in
|
||
Arbeit.
|
||
|
||
Die Worte in diesem File werden sowohl f<EFBFBD>r VDI- als auch f<EFBFBD>r
|
||
AES-Funktionen ben”tigt.
