This icould be, for examle, the calculation for an auto-entered MD5:

not IsEmpty ( Self ) ; Lower ( GetContainerAttribute ( Self ; "md5" ) ) ;

Agreed, but for my use of this function I would prefer the result to be empty where an empty parameter has been passed.

Thanks for the input!

Regarding empty string. When I try it, I get an error:

getContainerAttribute( ""; "MD5")
