Hi,
although I don't know why:
Function SEO_CLASS_GET_CL_NAME will give you the name of the include,
function SEO_CLASS_GET_INCLUDE_SOURCE called with INCTYPE = 'CU' will extract the source code with public section.
Bote: internally, all parts of the class are in different includes - not as seen in the source-code-based view in class builder.
Regards,
Clemens
