The Sozobon cc.ttp program assumes that you use a command shell that can pass arguments unmangled. The behavior you describe suggests that your command shell is upcasing the tail (arguments). That's trouble -- cc is case-sensitive, and jas may be as well. You can NOT run cc from the Desktop.

To position the text cursor (not the mouse pointer!) you can use the VT52 escape code: <esc>Y<row><column> as in: printf("\033Y%d%d", row, column) Plotting individual pixels is another matter entirely. You can use the Line A graphics routines (in assembler), but there is almost no publicly available documentation on Line A. Your best bet probably is to use the VDI output function v_pline(handle, count, pxyarray) and plot a line with only one point. -- Steve Yelvington, up at the lake in Minnesota ... pwcs.stpaul.gov!stag!thelake!steve
