PLOT Y(X)=<function of X> or PLOT X(T)=f(T),Y(T)=g(T)
plots a curve.
X (and T) can be any 'word' like 'time' in PLOT Y(time)=v*time^2/2.
The plotting area is selected by the XSCALE and YSCALE specifications.
Defaults are XSCALE=-10,0,10 and YSCALE=-10,0,10.
The range of X is given by X=<initial value>,<final value>,<step>.
If <step> is not given, (<final value>-<initial value>)/100 is employed
as the plotting step. If no range is given, limits of XSCALE are used.
For example,
PLOT X(t)=10*cos(t),Y(t)=10*sin(t) / t=0,6.283,0.2
plots a circle of radius 10.

The functions must be written according to the rules of editorial computing.
They may include parameters whose values are given in the edit
field in the form <name of parameter>=<value>.
For example,
PLOT Y(x)=x^n / n=1,4,1 XSCALE=-3(1)3 YSCALE=-100(50)100
plots 4 different power functions.
New options in SURVO MM described on the next page!

In SURVO MM it is possible to give ranges of the variable (X) and
parameters also in the form <initial_value>(<step>)<final_value>.
