If i am writing the following code in Maple 11 it gives me the postscript picture with a black frame around.

Why the option noborder is not working?

myPlot1:= plot(sin(x), x= 0..10, axes= boxed, color= black, scaling= constrained, view= [0..10, -5..5]):
plotsetup(
  ps,
  plotoptions= `noborder,width=5cm,height=5cm`,
  plotoutput= "myPlot1.eps"
);
plots[display](myPlot1);
plotsetup(default)

In Maple 11 I need to write define_external procedure with 23 arguments.

For example:
   test1 := define_external('myproc',
                                               N1::(integer[4]),
