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 <EFBFBD>bergabeparameter
|
|||
|
|
der einzelnen Funktionen sind unver<EFBFBD>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<EFBFBD>tigt.
