The sign is also used to denote "numbers of items". The sign is used for 1. Examples of multiple uses in the Amarna letters, is to address the Pharaoh, often as "servant-yours, at 2 Feet, .. I bow." An example of multiple uses in the Amarna letters, often the bowing down is done: " .. 7 and 7 times (I bow) !", with seven small strokes as units of number "1".
Many of the Amarna letters use glossenkeils, of two varieties: type 1: ?, and type 2: (gl (AL)). Type 2 is found in example letters: EA 364, EA 245, and EA 287. (In CDLI listings (Chicago Digital Library Initiative), it is represented in transcription as ":". Likewise in the Moran, William L. translations.) Type 1 can be found in Amarna example letter EA 147.
The type 2 glossenkeil, is a shortened version of the large-angled-stroke, type 2; (the long stroke of the sign is slightly, or majorly, foreshortened. In the Amarna letters, often down to 50 % of the "full stroke".). The high quality photo of EA 364, line 8, shows the length about 3/4 of a full stroke-length.
The ana, (di?) sign usage in the Epic of Gilgamesh is as follows: ana-(151 times); di?-(6); ti?-(6); and 1-(87 times).
