Dick Francis - Twice Shy

It was over coffee, when the girls were again swimming and Jane had disappeared into the house, that Ted said, 'How did you find me?'

I looked at him. 'Don't you mean why?'

'I suppose so. Yes.'

'I came to ask you to let me have copies of those tapes.'

He breathed deeply and nodded. 'That's what I thought.'

'And will you?'

He looked at the shimmering pool for a while and then said, 'Does Jonathan know you're asking?'

'Yeah. I asked him where the tapes were now, and he said if anyone knew, you would. You and only you, he said.'

Ted Pitts nodded again and made up his mind. 'It's fair. They're his, really. But I haven't any spare tapes.'

'I brought some,' I said. They're out in the car. Can I fetch them?'

'All right.' He nodded decisively. 'I'll change into dry clothes while you're getting them.'

I fetched the computer-type tapes I'd brought for the purpose, and he said, 'Six? You'll only need three.'

'Two sets?' I suggested.

'Oh. Well, why not?' He turned away. 'The computer's downstairs. Would you like to see it?'

'Very much.'

He led the way into the body of the house and we went down some carpeted stairs to a lower floor. 'Office,' he said succinctly, leading the way into a normal-sized room from which one could see the same wide view of London as upstairs. 'It's a bedroom really. Bathroom through there,' he pointed. 'Spare bedroom beyond.'

The office was more accurately a sitting-room with armchairs, television, bookshelves and pinewood panelling. On an upright chair by one wall stood a pair of well-used mountain climbing boots, with the latest in thermal sleeping bags still half in its carton on the floor beside them. Ted followed my glance. 'I'm off to Switzerland in a week or two. Do you climb?'

I shook my head.

'I don't attempt the peaks,' he said earnestly. 'I prefer walking, mostly.' He pulled open a section of the pine panelling to reveal a long counter upon which stood a host of electronic equipment. 'I don't need all this for the racing programs,' he said, 'but I enjoy computers…' and he ran his fingers caressingly over the metal surfaces with the ardour of a lover.

'I've never seen those racing programs,' I said.

'Would you like to?'

'Please.'

'All right.' With the speed of long dexterity he fed a tape into a cassette recorder and explained he was putting the machine to search for the file 'Epsom'. 'How much do you know about computers?' he said.

'There was one at school, way back. We played "Space Invader" on it.'

He glanced at me pityingly. 'Everyone in this day and age should be able to write a simple program. Computer language is the universal tongue of the new world, as Latin was of the old.'

'Do you tell your students that?'

'Eh… yes.'

The small screen suddenly announced 'READY?' Ted pressed some keys on the keyboard and the screen asked 'WHICH RACE AT EPSOM?' Ted typed DERBY, and the screen in a flash presented: EPSOM: THE DERBY. NAME OF HORSE?

He put in his own name and randomly answered the ensuing questions, ending with:

TED PITTS. WIN FACTOR: 24

'Simple,' I said.

He nodded. 'The secret is in knowing which questions to ask, and in the weighting given to the answers. There's nothing mysterious about it. Anyone could evolve such a system, given the time.'

'Jonathan says there are several of them in the United States.'

Ted nodded. 'I've got one of them here.' He opened a drawer and brought out what looked like a pocket calculator. 'It's a baby computer with quite elegant programs,' he said. 'I bought it out of curiosity. It only works on American racing, of course, because one of its bases is that all tracks are identical in shape, left-handed ovals. It is geared chiefly to prize money. I understand that if you stick to its instruction book religiously you can certainly win, but of course like Liam O'Rorke's system you have to work at it to get results.'

'And never back a hunch?'

'Absolutely not,' he said seriously. 'Hunches are hopelessly unscientific.'

I looked at him curiously. 'How often do you go to the races?'

'To the races themselves? Practically never. I watch them, of course, on television, sometimes. But you don't need to, to win. All you need are the form books and objectivity.'

It seemed to me a dry view of the world where I spent my life.

Those beautiful creatures, their speed, their guts, their determination, all reduced to statistical probabilities and microchips.

'These copies of yours,' he said, 'do you want them open, so that anyone can use them?'

'How do you mean?'

'If you like, you can have them with passwords, so that they wouldn't work if anyone stole them from you.'

'Are you serious?'

'Of course,' he said, as if he were never anything else. 'I've always put passwords on all my stuff.'

'Er, how do you do it?'

'Easiest thing in the world. I'll show you.' He flicked a few switches and the screen suddenly announced 'READY?'

'You see that question mark,' Ted said. 'A question mark always means that the computer operator must answer it by typing something. In this case, if you don't type in the correct sequence of letters the program will stop right there. Try it. See what happens.'

I obediently typed EPSOM. Ted pressed the key marked 'Enter'. The screen gave a sort of flick and went straight back to 'READY?'

Ted smiled. 'The password on this tape is QUITE. Or it is at the moment. One can change the password easily.' He typed QUITE and pressed 'Enter' and the screen flashed into WHICH RACE AT EPSOM?

'See the question mark?' Ted said. 'It always needs an answer.'

I thought about question marks and said I'd better not have passwords, if he didn't mind.

'Whatever you say.'

He typed BREAK and LIST 10-80, and the screen suddenly produced a totally different looking format.

'This is the program itself,' Ted said. 'See Line 10?'

Line 10 read INPUT A$: IF A$ = "QUITE" THEN 20 ELSE PRINT "READY?"

Line 20 read PRINT "WHICH RACE AT EPSOM?"

'If you don't type QUITE,' Ted said, 'You never get to line 20.'

'Neat,' I agreed. 'But what's to prevent you looking at the program, like we are now, and seeing that you need to type QUITE?'

'It's quite easy to make it impossible for anyone to List the program. If you buy other people's programs, you can practically never List them. Because if you can't List them you can't make copies, and no one wants their work pinched in that way.'

'Um,' I said. 'I'd like tapes you can List, and without passwords.'

'OK.'

'How do you get rid of the password?'

He smiled faintly, typed 10 and then pressed 'Enter'. Then he typed LIST 10-80 again, but this time when the program appeared on the screen there was no Line 10 at all. Line 20 was the first.

'Elementary, you see,' he said.

'So it is.'

'It will take me quite a while to get rid of the passwords and make the copies,' he said. 'So why don't you go and sit upstairs by the pool. To be honest, I'd get on faster on my own.'

Pleased enough to agree, I returned to the lazy bamboo loungers and listened to Jane talking about her daughters. An hour crawled by before Ted reappeared bearing the cassettes, and even then I couldn't leave without an instructional lecture.

'To run those tapes, you'll need either an old Grantley personal computer, and there aren't many of them about nowadays, they're obsolete, or any type of company computer, as long as it will load from a cassette recorder.'

He watched my incomprehension and repeated what he'd said.

'Right,' I said.

He told me how to load Grantley BASIC, which was the first item on Side 1 of the tapes, into a company computer, which had no language of its own built in. He again told me twice.
