Evaluate

The Evaluate function interprets the passed string as an expression, which is then translated and executed.

Syntax
Evaluate(Expression)
Return value
Type	Description
Long	Error code or 0 on successful execution
Parameter
Use	Name	Type	Passing	Description
Required	Expression	String	ByVal	Expression to be compiled and executed by the interpreter

Example:

Evaluate("MsgBox(""Hello World"")")

A message box appears with the text "Hello World".

Evaluate("Amount := 10")

The variable Amount gets the value 10

Another way to evaluate is to use reference variables:

For this example, a class variable "Length" of the type Double was created before.

Dim Ref As Reference

Ref.Expression := "Length"

If Ref.ExpressionInvalid <> 0 Then

MsgBox "Invalid expression."

Return

End If

Ref := 20.45

#Check of the assignment

MsgBox(Length)

The length variable now contains the value 20.45
