Exhibit A Cable to the Mexico City Station from CIA Headquarters, November 27, 1963. This document was released in full after a Board vote in 1995. The second line of typed text includes the crypts (or cryptonyms) "RYBAT" and "GPFLOOR." These crypts appear in the "slug line" and they are routing and sensitivity indicators. "GPFLOOR" is the crypt that refers to Lee Harvey Oswald. This same crypt appears in the first line of the second paragraph of text. CIA originally advised that GPFLOOR could not be released in the slug line although it could be released in the text of the cable.
