* rdata[5..8] DiskSpaceLimit (Lo-Hi, only for SDK 22/33)

* Parser comparison: ObjectID is read from the documented position
* for all three subfunctions. DiskSpaceLimit for 22/33 is not
* for all three subfunctions. DiskSpaceLimit for SDK 22/33 is not
* consumed by this prehandler; handle_after_bind() receives only the
