Michel, How about:

luRecordHook = This.RecordHook()
This.cHtml = This.cHtml + IIF(TYPE("luRecordHook") = 'C',luRecordHook,"")

>I have a class which contains a method called RecordHook(). When that class is instantiated, it may or not contains some code in the RecordHook() method. However, in the main class, I have this code:
>
>

>This.cHtml=This.cHtml+This.RecordHook()

>
>This code gets executed even if there is no code in RecordHook(). I would prefer to have the RecordHook() method, when it contains some code to have this as the last line of its code:

>RETURN lcHtml

>However, if there is no code, this will fail.
