Except as Listed

The man had a revolver and a sheet of paper, and it was the paper he looked at.

Ruth Szabo had started the dump at twelve forty, as she did every Wednesday night, and had sat down at the console with a cup of coffee to watch the first reel fill. The dump copied everything on the disk to tape, one user's files after another, and took two hours and eleven minutes if nothing went wrong. It was the dullest job in the building. That was why she did it herself. She did not like to give the dull jobs to people who would stop paying attention.

He came in through the machine-room door without knocking. He was perhaps forty, in a grey raincoat that was dry, so he had come by car and not walked up the hill. She knew his face. He had been through in September with two men from a firm in Sunnyvale that wanted to buy time on the machine, and he had asked sensible questions about the disk and nothing else, and she had liked him for it. His name was Pruett. He held the revolver low, beside his coat pocket, as if he would rather not be seen with it.

"Please don't get up," he said. "I've taken the telephone off the wall in the hall. I don't want to hurt you. I want a copy of some files, and then I'll go."

He unfolded the paper. It was a single sheet of yellow legal paper written on both sides in a small, upright, engineer's hand, not his own: she could tell because he read it the way a man reads a recipe written by his wife, slowly, with his lips almost moving.

"You're going to mount this," he said, and put a reel of tape on the desk beside her coffee. It was a new reel, still in its plastic case, with the white write-ring already pressed into the groove at the back of the hub. Whoever had written the sheet knew that much. No ring, no writing; the drive would refuse. "On drive two."

She looked through the glass at the tape drives. There were four, tall grey cabinets with their reels behind smoked doors and the vacuum columns below, where the tape hung in loops and trembled. Drive two was turning. The dump was on it.

"Drive two is busy," she said.

He looked at the sheet. He turned it over and looked at the back. She watched him find nothing.

"Use another one."

"The commands on your paper say drive two?"

"Yes."

"Then if I mount it on drive three and type what is on the paper, it will write to drive two. It will write your files on the end of the dump. You'll take away a blank reel."

He thought about that. She could see him decide that she was telling the truth, and she could see that he did not like having to decide it.

"Then stop the dump."

"I have to type a command that isn't on your sheet."

"Tell me what it is first."

"KILL DUMP."

"What does it do?"

"It stops the dump."

"Does anybody see it?"

She had the answer ready, and it was true, so she gave it. "The console prints it." She pointed at the Teletype in front of her, its paper folding out of the back into the box on the floor.

He stood behind her chair, close enough that she could smell the rain on his collar, and watched her type the nine characters. He watched as if he could read them. She supposed that he could read them; he could not read what they meant. The machine stopped drive two in the middle of a user's files. The reels spun down and stood still. The console printed:

00:58 DUMP KILLED BY OPR AT CONSOLE. REEL 2 INCOMPLETE.

It printed the same line on every Teletype attached to the machine, because that was what KILL did. She had written that part of the dump program herself, two years ago, after a night operator had killed a dump and gone home, and the users had come in at eight and found the disk damaged and no tape to restore from. Anyone logged in should know that the dump had stopped. Nobody had ever asked to change it. Nobody had ever needed to know it except the people who ran dumps.

At one in the morning on a Wednesday, there were three users logged in. Two were jobs that ran by themselves. The third was Ezra Hale, at the Teletype in his kitchen, three miles away, connected through the telephone and a modem the size of a breadbox, running a theorem-prover that he had started at nine and would not leave. Ezra did not sleep while his programs ran. He sat up and read the output and argued with it.

"Take the dump tape off," Pruett said.

She went through into the drive room. He came after her and stood in the doorway, so that he could see her and the console at once. She opened the smoked door of drive two, pressed the rewind button, waited for the tape to run home onto its reel, took the reel off the hub, and laid it on top of the cabinet. She took his new reel out of its case. She checked the ring with her thumb. She put the reel on, threaded the leader through the head and onto the take-up reel, closed the door, and pressed LOAD. The vacuum pulled the tape down into the columns in two smooth loops. She pressed READY, and the light came on.

Behind Pruett, the console began to type.

They both went back. It was a message, not a machine report, and it was in capitals, because the Teletypes had no other kind:

01:01 FROM EH: WHY KILL DUMP. ITS WEDNESDAY.

Pruett read it twice. He looked at his sheet. His finger went down the back of it, near the bottom, and stopped.

"If anyone asks by message," he read aloud, "she types: TESTING DRIVE 2. GOOD NIGHT. Nothing else." He looked at her. "Who is EH?"

"A programmer. He's at home."

"Can he see what you're doing?"

"He can see what the machine tells him."

He held the sheet next to the keyboard so that she could copy it exactly, and she did. TO EH: TESTING DRIVE 2. GOOD NIGHT. He read each character as it came. When she had finished he had her stop, before the carriage return, while he checked it again. Then he nodded and she pressed RETURN, and the message went three miles down the hill.

She did not know what Ezra would do with it. That was the difficulty. She could not put anything into the message that Pruett would not see, and she could not put anything into it that was false, because he would ask her what each word meant and she was not a good liar and did not intend to start learning at gunpoint. But the message was not all that Ezra had. He had the line about the dump. He had the time. He had the fact, which no sheet written in Sunnyvale could contain, that she had never once in two years killed a dump to test a drive, because a drive could be tested at any hour of the day, and a dump killed at reel two meant starting again from reel one. He had what she had said and what she had not said, and the second was larger.

It was also possible that he would type OK and go back to his theorem-prover. People did not, as a rule, suppose that something was badly wrong when a simpler explanation was available. That was sound practice. She practised it herself. Ezra might decide that she was tired, or that something had broken that she did not want to explain at one in the morning.

The console typed.

01:03 FROM EH: OK

Pruett let his breath out, quietly, through his nose.

Ruth looked at the two letters for some time. In three years she had never known Ezra Hale to say OK to anything. He would answer a proof with a counterexample and a counterexample with a request for definitions, and when he had nothing to object to, he said GRANTED, as if he were giving something up. If she had sent him a message saying that the sun had risen he would have asked her which horizon. He had read TESTING DRIVE 2 and GOOD NIGHT and not asked what she meant by testing. He had not asked anything at all.

"Go on," Pruett said. "Item four."

Item four was the copy. She typed it as it was written: the command, the name of the project directory, the drive. The project was a Navy contract, four people on the second floor writing programs to sort the noises in hydrophone recordings into ships and whales and the sea. She had never been told that it was secret and had always assumed that it was. The files were not large. The machine began to read them from the disk and write them to the tape, and drive two turned in short jerks, a block at a time, and the loops in the vacuum columns rose and fell.

"How long?" Pruett said.

"Six or seven minutes."

He looked at his watch and then at the sheet, and she understood that the sheet had told him five.

At 01:07 the line printer in the corner started up without warning. It was the size of a chest freezer and it made a noise like a man running a stick along railings, very fast, and Pruett turned toward it with the revolver up before he knew he had done it. Ruth kept still. The console printed JOB 14 DONE. 3 PAGES LPT., and the printer ran three pages of somebody's figures out of its mouth and stopped.

"What was that?"

"One of the jobs that runs by itself. Somebody's tables. It finished."

"Is it on here?" He meant the sheet, and he was already looking. It was not. She could have told him that it would not be, that nobody could have written down every job that might finish while he stood there and every page it might print, and that whoever had written his sheet had not tried. She did not tell him. He lowered the revolver slowly to his side, as if he were putting it away in a drawer that would not quite close.

"Does anything else do that?"

"The drives. The disk, when it seeks. The air conditioning comes on at about half past one. It makes a bang in the duct over the door."

He looked up at the duct. "Thank you," he said, and she saw that he meant it, and that he was more frightened than she was. It did not make her feel safer. A frightened man with a sheet of instructions would do what was on it. A frightened man who had come to the end of it might do anything.

The telephone in the hall did not ring. She noticed that, and then she noticed that it could not ring, because he had taken it off the wall. If Ezra had telephoned after he typed OK, which was what anyone would do next, he would have heard it ring at the other end and nobody answer, or he would have heard nothing, depending on what Pruett had done to the wire. Either way that was a second thing to set beside the first. She did not know whether Ezra had telephoned. She found that she had put her hands flat on the desk on either side of the keyboard, and she left them there.

At 01:11 the console printed COPY COMPLETE. 41 FILES. 1 REEL. Pruett bent and read it against the sheet, letter by letter, and seemed satisfied. Item five said to rewind and unload. She went through and did it, and brought him the reel in its plastic case, and he put it in the inside pocket of his raincoat, where it made a square shape over his heart.

Item six said: Have her type LOGOUT. She was not logged in. The console operator never logged in; the console was the machine's own terminal. She told him so.

He looked at the sheet for a long time. Then he folded it in half and in half again and put it in his trouser pocket, and she saw that he had come to the end of what it could do for him.

"Sit down," he said. "Hands behind the chair."

He had brought cord, the waxed kind electricians use for lacing cable, and he tied her wrists to the back of the chair and her ankles to its legs, carefully and not very tightly. He tied knots like a man who had read about tying knots. When he had finished he stood back and looked at her, and for a moment he seemed about to say something to her that was not on any sheet.

"There's a woman who cleans at six," Ruth said. "She'll find me."

"Good," he said, and went out.

She heard his steps down the corridor, and the front door, and then the car. It started the second time. There was one road down from the building, a narrow one with two bends, which met the county road at the bottom by a stand of eucalyptus. She listened to the engine go down through the first bend.

At the second bend the engine note changed. She heard brakes, and a door, and after a moment, very small at that distance, a man's voice raised and another man's voice answering it. Through the high window over the drives she could see the tops of the eucalyptus, and on them the slow red turning of a light.

The console began to type. The chair was turned a little toward it, and she could just read the line as it came.

01:19 FROM EH: RUTH DEFINE TESTING
