A few questions about skill?

**********************************************************************************
1--> What is the best approach to traverse through layout hierarchy (which is having mosaics)
   including opening, modifying, saving and closing cellview ...?

   /*******************flatten pcells, convert paths to polygon and merge all shapes************************/
   procedure(size_traverse(@optional (cv deGetEditCellView()))
  FLATTEN_MPP(cv)  ;; consists rodGetNamedshapes() and rodUnNameShape() functions
  path2polygon(cv) ;; consists dbConvertPathToPolygon() function

  foreach(inst cv~>mosaics
      if(member(car(inst~>instanceList)~>libName list("tcbn65gplus" "tsmcN65")) then
          leFlattenInst(inst 31 t nil nil)
      else
      if(ddGetObj(car(inst~>instanceList)~>libName car(inst~>instanceList)~>cellName car(inst~>instanceList)~>viewName) then
          mas = dbOpenCellViewByType(car(inst~>instanceList)~>libName car(inst~>instanceList)~>cellName car(inst~>instanceList)~>viewName "" "a")
          size_traverse(mas)
          dbSave(mas)
          dbClose(mas)
      );if
      );if
  );foreach

  foreach(instp cv~>instances
      if(member(instp~>libName list("tcbn65gplus" "tsmcN65")) then
          leFlattenInst(instp 31 t nil nil)
      else
      if(ddGetObj(instp~>libName instp~>cellName instp~>viewName) then
          masp = dbOpenCellViewByType(instp~>libName instp~>cellName instp~>viewName "" "a")
          size_traverse(masp)
          dbSave(masp)
          dbClose(masp)
      );if
      );if
  );foreach
);size_traverse
   /*******************flatten pcells, convert paths to polygon and merge all shapes************************/

When I run this code by commenting dbSave() and dbClose() statements everything is going fine.
(And finally I am doing closedata by saving all to complete the desired task)
But when I include these statements I am getting the following error ...

*Error* dbSave: Invalid cellView - db:294651948

I am not able find out this invalid dbId that encountering dbSave() statement.

2--> Is file manipulation slow in SKILL compared to tcl/perl/shell ...?

3--> How to make 'SKILL' code faster (while dealling with files) ...? (A simple example please...!)

4--> In SKILL Can we create pulldown menu for a form which has created by hiCreateAppForm() (like File-->Open-->Close) ...?

5-->
hyper1 = hiCreateHypertextField(?name 'hyper1  ?value "<A>(10:0 10:20)</A>" ?callback "my_proc")
myForm= hiCreateAppForm(
          ?name 'myForm
          ?fields list(hyper1)
          ?formTitle "HyperText demo form..."
          ?callback ""
          ?buttonLayout 'OKCancelApply
          ?initialSize t
          )
hiDisplayForm(myForm)

How to add another hypertext value beside (10:0 10:20) ...?
In the above example my_proc is a simple pop-up menu. I need this pop-up displayed at the cursor. But this pop-up displaying at a different location.
I hope the problem is understandable. If not I will come up with some more information.
