If the DAT image pointer is to the entire DAT, make D+X equal to the process address for data. If the DAT image is not the entire image (64K), you must adjust D+X relative to the beginning of the DAT image. Using D+X lets you keep a local pointer within a block, and also lets you point to an offset within the DAT image that points to a specified block number. </li> </ul> <p><em>krn</em></p></div>LothanFri, 27 Jun 2014 23:20:54 -0000https://sourceforge.net5e59f750f919b2f3b18cb5ff18f21b05d004a1a0
