A class property (array or not) can only be passed by value to a function or a method. You can pass the name of the array to the method (this.DelimitedStringToArray(this.DelimitedString, ':', "this.ArrayProperty"))and use macro substition in the method to access the array or use a temporary array in the method and ACOPY() it to the array name passed as a parameter.

>I have a method inside a class that will convert a delimited string into an array. This method has three parameters in this order: tcString, tcDelimiter, tcArrayName
>
>I have also array properties inside the same class. However, I have an error when I passed the array property.

>Example:
>Init Method:
>this.ArrayProperty(1)=''
>this.DelimitedString ='String1:String2:String3'
>this.DelimitedStringToArray(this.DelimitedString,':',@this.ArrayProperty)
>
>The third line will cause an error THIS alias not found. I have resolved this by creating a local temporary array and pass this temporary array instead, then issue an ACOPY().
