You can use GD2 colours via S*BASIC with WM_BLOCK instead of BLOCK etc. but presumably these do not rely in any way on the vectors of WMAN2. In fact WMAN2 is provided just for assembler programmers isn't it? George _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
