Meaning is whatever you assign and no computer can analyze it simply from letter group. Give a computer enough groups and a rational theory involving meanings or subjects for meanings, and it will eventually worry it out because meanings themselves will show patterns. But is a problem of different kind on more difficult level.
Code we selected was commonest commercial codebook, used both on Terra and in Luna for commercial dispatches. But we worked it over. Prof and Mike spent hours discussing what information Party might wish to send to its agent on Terra, or receive from agent, then Mike put his vast information to work and came up with new set of meanings for codebook, ones that could say “Buy Thai rice futures” as easily as “Run for life; they’ve caught us.” Or anything, as cipher signals were buried in it to permit anything to be said that had not been anticipated.
Late one night Mike made print-out of new code via Lunaya Pravda’s facilities, and night editor turned roll over to another comrade who converted it into a very small roll of film and passed it along in turn, and none ever knew what they handled or why. Wound up in Stu’s pouch. Search of off-planet luggage was tight by then and conducted by bad-tempered Dragoons–but Stu was certain he would have no trouble. Perhaps he swallowed it.
Thereafter some of LuNoHo Company’s dispatches to Terra reached Stu via his London broker.
Part of purpose was financial. Party needed to spend money Earthside; LuNoHoCo transferred money there (not all stolen, some ventures turned out well); Party needed still more money Earthside, Stu was to speculate, acting on secret knowledge of plan of Revolution–he, Prof, and Mike had spent hours discussing what stocks would go up, what would go down, etc., after Der Tag. This was Prof’s pidgin; I am not that sort of gambler.
But money was needed before Der Tag to build “climate of opinion.” We needed publicity, needed delegates and senators in Federated Nations, needed some nation to recognize us quickly once The Day came, we needed laymen telling other laymen over a beer: “What is there on that pile of rock worth one soldier’s life? Let ’em go to hell in their own way, I say!”
Money for publicity, money for bribes, money for dummy organizations and to infiltrate established organizations; money to get true nature of Luna’s economy (Stu had gone loaded with figures) brought out as scientific research, then in popular form; money to convince foreign office of at least one major nation that there was advantage in a Free Luna; money to sell idea of Lunar tourism to a major cartel–
Too much money! Stu offered own fortune and Prof did not discourage it– Where treasure is, heart will be. But still too much money and far too much to do. I did not know if Stu could swing a tenth of it; simply kept fingers crossed. At least it gave us a channel to Terra. Prof claimed that communications to enemy were essential to any war if was to be fought and settled sensibly. (Prof was a pacifist. Like his vegetarianism, he did not let it keep him from being “rational.” Would have made a terrific theologian.)
As soon as Stu went Earthside, Mike set odds at one in thirteen. I asked him what in hell? “But, Man,” he explained patiently, “it increases risk. That it is necessary risk does not change the fact that risk is increased.”
I shut up. About that time, early May, a new factor reduced some risks while revealing others. One part of Mike handled Terra-Luna microwave traffic–commercial messages, scietitific data, news channels, video, voice radiotelephony, routine Authority traffic–and Warden’s top secret.
Aside from last, Mike could read any of this including commercial codes and ciphers–breaking ciphers was a crossword puzzle to him and nobody mistrusted this machine. Except Warden, and I suspect that his was distrust of all machinery; was sort of person who finds anything more involved than a pair of scissors complex, mysterious, and suspect–Stone Age mind.
Warden used a code that Mike never saw. Also used ciphers and did not work them through Mike; instead he had a moronic little machine in residence office. On top of this he had arrangement with Authority Earthside to switch everything around at preset times. No doubt he felt safe.
