StrRightBack ,StrLeftback etc. should always return a string

PROBLEM:
In an import method I had to detect that the combination of StrLeftBack(StrRightBack( HTMLrow$,"<") ,">") returned not, as expeted, an empty string "" but Empty.
I had to write a test for each HTML value wether it IsEmpty or not.

REASON:
This is counterintuitive and a cause for a good chance to get unexpected errors. In your help about Empty (DECS) is specifically written that :
"In Domino® Enterprise Connection Services (DECS) and in HCL Enterprise Integrator (HEI), empty data in a Notes® rich text or Text field is not set to NULL when it is transferred. It is transferred as "". To set empty data to NULL requires that you write a LotusScript® routine or a stored procedure. "
Thats exactly the opposite case. Thus I think the general line in LS is to return an emtpy String and not Empty.

SOLUTION:

Please ensure that StrLeft,Strright,StrLeftBack and StrRightBack can not return Empty as value but a string "", as all other string functions in LS do, if the result string is empty.
