See the image below. I'm trying to understand what this is saying, particularly the "12"-16" and the reference to "22 Trans to Repl Bn". also what does "GO 100 does not apply auth GO 111"
I believe I may have some info for you. Browsing through the document you seem to be looking at (but not the specific page)
seems to show this is some form of monthly log. The other numeric entries would appear to correspond to days of the month. I am guessing that the numbers with quotes indicate actual combat days.
Which means this 22 is the date of the transfer to the Replacement Battalion (Bn).
GO is General Order, and GO 100 is concerning record keeping requirements, while GO 111 is concerning replacement troops:
In addition to the combat divisions assigned to each corps and the corps troops. a Replacement Battalion will be organized in each corps. This battalion is under the command of the corps commander and will be designated as the " __ Corps Replacement Battalion."
The above is from pg. 386 of UNITED STATES ARMY IN THE WORLD WAR 1917-1919 General Orders, GHQ, AEF Volume 16
