Rechnen
Der Inhalt einer String Variablen kann nicht direkt für Rechen Operationen verwendet werden, es ist also erforderlich das eine Stringvariable erst in eine Variable anderen Typen umgewandelt werden muss.
Ist z.B. folgender String vorhanden

Dim  S as String * 10
Dim  T as Integer

S= 123456
so muss dieser String folgendermaßen gewandelt werden um damit zu rechnen.

T = Val(S)
Print T
