                        \ If we get here then we are done processing this
                        \ object, so now we check whether there are other
                        \ objects to process:
                        \
                        \   * If the object is in a group (i.e. the object ID
                        \     is 6, 7, 8 or 9) and there are other objects to
                        \     process in the group, we loop back to process them
                        \
                        \   * If this is object 30, then we check whether we
                        \     have processed all 8 items in its group, and if
                        \     not, we loop back to process the next one (see
                        \     part 10)
                        \
                        \   * If this object is not caught by the above, then
                        \     we finally return from the subroutine (see part
                        \     11)

 JSR NextObjectGroup    \ If this object is in an object group, i.e. Y is 6, 7,
                        \ 8 or 9, then increment the object's group number

 BCC objc11             \ If the C flag is clear then this object is not part of
                        \ an object group, so jump to objc11 to skip the
                        \ following

                        \ This object is part of an object group, so now we move
                        \ onto the next object in the group

 DEC objCount           \ Decrement the loop counter to move on to the next
                        \ object in the group

 BEQ objc12             \ If we have processed all 8 items in the group, jump
                        \ to objc12 to return from the subroutine

 JMP objc2              \ Otherwise loop back to objc2 to process the next item
                        \ in the group
