The new field will be created with the same number of elements as another field on the same Lotus Notes document. I used this mainly for the purpose of adding an additional field for document revision histories.

Sub Initialize
Dim s As New NotesSession
Dim db As NotesDatabase 
Dim collection As NotesDocumentCollection
Dim doc As NotesDocument
Dim edits As Variant, newField() As String
Dim n As Integer, docCount As Integer


Set db = s.CurrentDatabase
Set collection = db.unprocessedDocuments
Set doc = collection.GetFirstDocument
While Not doc Is Nothing
Redim newField(0)
docCount = docCount + 1
 
If doc.HasItem("OtherField") Then
If doc.OtherField(0) <> "" Then
edits = doc.GetItemValue("OtherField")
For n = 0 To Ubound(edits)
Redim Preserve newField(n)
newField(n) = "Initial value"
Next
End If
End If
  
doc.NewField = newField
doc.Save True, False
 
Set doc = collection.GetNextDocument(doc)
Wend

Print "Processed " & docCount & " documents"
End Sub
