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.
