The block is specified by the DAT image in (Y), offset by (X). The call assumes that the DAT image pointer is to the actual block desired, and that X is only an offset within the DAT block. The value in Register X must be less than the size of the DAT block. NitrOS-9 does not check to see if X is out of range. </li> </ul> <p><em>krn</em></p></div>LothanFri, 27 Jun 2014 23:07:07 -0000https://sourceforge.net178045257fc408c3cf9f40c9ff60777eb615e9d0
