If I can only remember/read ONE thing: what "STOP" means.
Mrs Jay said to Blue "That's a cleva chap, he's remembered all the places
where he must stop". But what does 'read' mean.
BTW I've started listening [TextToSpeech} Wirth's po.pdf, and extracted some

 eye. Consequently, the computer's visual output unit must be properly
 matched with the human eye. ..
