If this will be a editing operation (which can be undone and redone), you

can call

rve.SetSelectionBounds(ItemNo, rve.GetOffsBeforeItem(ItemNo),

ItemNo, rve.GetOffsAfterItem(ItemNo));

rve.DeleteSelection;

About DeleteItems

- you need to call Format after DeleteItems before displaying document or

before calling any method for editing;

- it's a dangerous method, it can create invalid documents if used

improperly (see "Valid Documents" topic in the help file)
