In jedem NewBasic Programm werden vom NewBasicBuilder eine Anzahl schon festgelegter Konstanten definiert. Diese stehen dem Programmierer zur Verfügung. Wer sie kennt, muß sich nicht überlegen, ob er entsprechende Konstanten selbst definieren muß.
Die Konstanten sind in der Subroutine sub duplo_ui_ui_ui() festgelegt. Die Bedeutung der Konstanten erklärt sich durch passend gewählte Bezeichnungen.
