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.

I understand that I should do something like this if I want this to work all the time from the main code:

This.RecordHook()
* The HTML code is now appended to This.cHtml

and from the RecordHook() method in its last line:

This.cHtml=This.cHtml+lcHtml

But, as I would prefer to have the RecordHook() method to return the HTML, would it there be a way to determine if some code is present in RecordHook() so I could have something like this:

IF This.RecordHook.CodeIsPresent
   This.cHtml=This.cHtml+This.RecordHook()
ENDIF
