'Diesen Quelltext stelle ich ausschließlich für nichtkommerzielle Zwecke zur Verfügung.
'Änderungen und Erweiterungen müssen mit Hinweis auf den Urheber und einschränkungen des Verwendungszwecks veröffentlich werden!
'Der Programmname "Rechenknecht" ist vorläufig und stellt keinen markenrechtlichen Besitzanspruch seitens des Urhebers dar!
'Tastenbelegung:
'ENTER : Einfache Ergebnisanzeige (nur 1. Eingang wird dargestellt)
'0 : Wert-Eingabefeld (Ein Baustein das am ehesten einer Konstanten gleichkommt)
'+ : + (Alle Eingänge werden addiert)
'- : - (Alle Eingänge ab dem 2. werden vom 1. Eingang subtrahirt)
'* : * (Alle Eingänge werden miteinander multipliziert)
'/ : / (1. Eingang wird durch 2. dividiert, das ergebnis daraus wird durch den 3. dividiert, usw...)
'1 : SQR (Alle Eingänge werden addiert und dann die Wurzel aus dem Ergebnis gezogen)
'2 : 1/x (1 wird durch die addition aller Eingänge dividiert)
'DIGITALTECHNIK:
'3 : UND
'4 : ODER
'5 : INVERTER
'andere Tastenfunktionen:
'a : Erstellt einen neuen Baustein (default = Werteingabefeld)
's : Stop/Start (Anfangszustand des Programms ist gestoppt, soll das Programm anfangen zu rechnen, dann bitte die "s" Taste drücken!)
'PgDown : Einen Schritt weiter Rechnen (nur im gestoptten Zustand sinnvoll)
'd : Löscht einen Baustein
'v : Weisst einem Baustein einen Wert zu. (Sinnvoll eigentlich nur bei Werteingabefelder (Taste 0))
'f : dreht den Baustein von links auf rechts
'linke Maustaste : Verbindung ziehen. (Beim anklicken wird der Ausgang des Bausteins gewählt, beim loslassen wird der eingang eines anderen Bausteines gewählt)
'Zieht man zwischen 2 Bausteinen eine Verbindung obwohl dort bereits eine besteht, wird die bestehnde gelöscht!
'rechte Maustaste : Verschieben eines Bausteines
