I am trying to select (and delete) a variable length string of text
downloaded from a web database.  The range always begins at the start of the
document and ends after a constant and unique phrase (e.g. "EndText").

How do I select the range between the starting and ending points?

Thanks in advance!

You can use the following to delete that range:

Dim oRng As Range
With Selection
    .HomeKey unit:=wdStory
    With .Find
        .ClearFormatting
        .Text = "EndText"
        .Execute
        Set oRng = ActiveDocument.Range _
            (Start:=ActiveDocument.Range.Start, _
            End:=Selection.Range.End)
    End With
End With
oRng.delete
