STEERING THE PC
  1. this is the only use of latent or random reads. You see a read the same as the instant read occurring again when you are not speaking but after you have found a whole thought reacting you say, "There" or "That" and the pc, seeing what he or she is looking at as you say it recovers the knowledge from the reactive bank and gives the data and the whole thought clears or has to be further worked and cleared. (HCOB 25 May 62)
  2. each time the needle twitches the auditor says, "That" or "There" to help the pc see what is twitching. This prompting is the only use of latent reads in Scn. (HCOB 3 May 62)
