plotchar.92p

This routine accepts a character and two lists of equal length which are 
the 1st and 2nd coords of points and uses the current graphing mode to
plot the character at each point.

No check is made that the lists are of equal length.


unitroot.92p

This routine accepts two lists lx and ly which are the 1st and 2nd
coords of the n-th roots of some complex number. It then plots the
circle they lie on and the points themselves.

If the lists are not the same length the program exits without comment.
No check is made that the points actually ARE n-th roots. The circle
is obtained by the modulus of the first point. The function sets the
calculator to PARAMETRIC mode and turns off any active plots.
