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.
