how to run a m file as in MatLab?

[yiu-man wong]

In MatLab, one can write a M file with a name, e.g. plotDefinedFunction.
Then typing the name, plotDefinedFunction, in the workspace will run the file.
Does Scilab has this important feature?

//filename: plotDefinedFunction
function f = myquadratic ( x )
   f = x^2
 endfunction
  // 
  xdata = linspace ( 1 , 10 , 50 ); 
  ydata = myquadratic ( xdata );
  plot ( xdata , ydata , "+-" ) 
  xtitle ( "My title" , "X axis" , "Y axis" );

Thanks.
