sure, cf. below

here's a new version of your script:


// set option for all views
View.NormalRaise = 0.2;

// merge views
Merge "postLagrangeApp.msh";

General.Trackball = 0;
General.RotationX = Asin(Tan(Pi/6)) * 180/Pi;
General.RotationY = 45;
General.RotationZ = 0;

// get post-processing view count
nbViews = PostProcessing.NbViews;

// hide all views
For index In {0:nbViews-1}
   View[index].Visible = 0;
EndFor

For index In {0:nbViews-1}
   // show relevant view
   If(index)
     View[index - 1].Visible = 0;
   EndIf
   View[index].Visible = 1;

   // print picture
   Print Sprintf("plateMode-%g.png", index);
EndFor

"Include" == verbatim include the contents of the file at the location 
of the command (so you can only "Include" script files, i.e., files that 
can be parsed)

"Merge" == same as "File->Merge" in the GUI
