Issues on multiple Row Deletion using FOR Loop.

While deleting multiple rows in a datawindow, you cannot simply use a For..Next statement loop from top to bottom as when you delete a row, the rowcount is changed. 

Following will throw an Error

Long ll_RowCount, ll_Start

ll_RowCount = dw_1.rowcount()

For ll_Start = 1 to ll_RowCount
    if dw_1.getitemstring(ll_Start,'Status') = 'D' then
        dw_1.deleterow()
    end if
Next

The correct script should like the follow.
Example1:
For ll_Start = 1 to dw_1.rowcount()
   if dw_1.getitemstring(ll_Start,'Status') = 'D' then
      dw_1.deleterow()               
      ll_Start--                    // adjust pointer
   end if
Next

Example2: On Reverse Order

ll_RowCount = dw_1.rowcount()
For ll_Start = ll_RowCount to 1 step -1
   if dw_1.getitemstring(ll_Start,'flag') = 'D' then
      dw_1.deleterow()
   end if
Next
