2 Die Routinen in dieser Library entsprechen dem, was auch dem
|
|||
|
|
3 Pascal-, C- oder Modula-Programmierer zur Verf<72>gung steht.
|
|||
|
|
4 F<>r eine genaue Beschreibung der einzelnen Routinen verweisen
|
|||
|
|
5 wir auf die GEM-Dokumentation des ST-Entwicklungspaketes bzw.
|
|||
|
|
6 entsprechende Literatur.
|
|||
|
|
7
|
|||
|
|
8 Aus diesem Grunde wurden die - teilweise kryptischen - Namen
|
|||
|
|
9 von Digital Research beibehalten; auch die <20>bergabeparameter
|
|||
|
|
10 der einzelnen Funktionen sind unver<65>ndert geblieben.
|
|||
|
|
11 Der Aufbau einer FORTH-Library mit 'Super-Befehlen' ist in
|
|||
|
|
12 Arbeit.
|
|||
|
|
13
|
|||
|
|
14 Die Worte in diesem File werden sowohl f<>r VDI- als auch f<>r
|
|||
|
|
15 AES-Funktionen ben<65>tigt.
