Cursor For Loops

Reading Oracle PL/SQL by Steven Feuerstein I find that it is a mortal sin to RETURN in the middle of a cursor for loop, although the author does not give a solid explanation of why, except to say that this is bad programming practice. Does anyone have a more thorough explanation?

Thanks

P.S I initially thought that the cursor would not get closed but on testing I find that it does get closed Received on Wed Apr 22 1998 - 23:45:56 CDT
