Weighing 999 With a Height of 89

A member of the "Genealogy Tip of the Day" group on Facebook located this reference in the "U.S. World War II Army Enlistment Records, 1938-1946," on Ancestry.com for a James L. Dozier that indicated a height of 99 and a weight of 999 as shown below.

Obviously the measurements are not in inches and are not correct. It's possible that a description of this database at the National Archives indicates what these unusual numbers mean. It seems reasonable that they obviously incorrect numbers are some sort of code to indicate something else.

We'll see if we can get the answer and follow up.

[note: it appears that this error may be due to a card read error on the card that was punched to store the data.]
