Press Release key.
Press Start key.
Explanation
Typewriter is conditioned to enter data into core storage, beginning at location 00000.
Enter instructions to read numerically from typewriter, beginning at the first position of program storage (xxxxx), and branch to first program instruction.
Releases typewriter.
The Read Numerically instruction, entered in step 2, is executed.
As each character is typed, it is stored at location xxxxx and succeedingly higher-numbered core storage positions.
Terminates read instruction.
The next sequential instruction, which is the branch to the first program instruction at xxxxx, is executed.
Explanation
Typewriter is conditioned to enter data into core storage, beginning at location 00000.
Enter instruction to read numerically from paper tape reader, beginning at the first position of program storage (xxxxx), and branch to first program instruct ion.
Release typewriter.
The Read Numerically instruction, entered in step 2, is executed. The EL character punched in the tape causes a termination of the read in-struction and execution of the next sequential inin-struction (branch to first program instruction, which was entered in step 2).

Press Re lease key.
Press Start key.
Explanation Halts processing and initiates manual mode.
The address of the next instruction in sequence is saved in Product Address Register 1 (PR-1).
Typ.ewriter is conditioned to enter data into core storage, beginning at location 00000.
Enter instructions to read numerically from typewriter beginning at the first position of data entry (xxxxx), and branch to address saved in PR-1 (step 2).
Re leases typewriter.
The Read Numerically instruction, entered in step 4, is executed.
As each character is typed, it is stored at location xxxxx and succeedingly higher-numbered core storage positions.
Terminates Read instruction.
The next sequential instruction, which is Branch Back (step 4) to the address saved in PR-1 (step 2), is executed, and processing is resumed.
Explanation
Typewriter is conditioned to enter data into core storage, beginning at location 00000.
Enter instruction.
Write Alphamerically, beginning at xxxxx and continuing until a record mark is sensed, or,
Write Numerically, beginning at xxxxx and continuing. until a record mark is sensed, or,
Write (Dump) Numerically, beginning at xxxxx and continuing until location 19999 is printed or the Release key is depressed.
Releases typewriter.
Instruction entered in step 2 is executed.
Check Program Step Sequence and Operation Operator Action
1. Press Stop key.
2. Press SIE key.
3. Press SC E key.
4. Press SIE key.
Explanation Halts processing and initiates manual mode.
Each depression causes the execution of one instruction.
The Op code and the address of the next instruction to be executed are displayed in the Op register and MAR.
The instruction displayed in step 3 is executed. Steps 3 and 4 can be alternated to display succeeding instructions.
Reset Storage to Zeros Operator Action 1. Press Stop key.
2. Press I nsert key.
3. Type: 260000800009 4. Press Release key.
6. Press I nstant Stop key.
Explanation Halts processing and initiates manual mode.
Typewriter is conditioned to enter data into core storage, beginning at location 00000.
Enter instruction to transmit field from location 00009 to 00008.
The instruction entered in step 3 is located at 00000-00011. The zero at 00009 is transmitted to 00008. Since the next location read is always the zero pre-viously transmitted, there is no flag bit to halt the operation. Approximately 0.8 of a second is required to clear 20,000 positions of core storage. A Transmit Field Immediate instruction or Transmit Record instruction may be used in the same manner.
The operation is stopped with the machine in manual mode.
Display P and Q Addresses

Operator Action Explanation
Press Stop key. Halts processing and initiates manual mode.
Press S I E key until the instruction that contains the desired address is next.
Press the SeE key eight times.
Press Reset key.
Turn MARS switch to OR-1 (Operand Address Register 1) and depress the Display MAR key.
Turn MARS switch to OR-2 (Operand Address Register 2) and depress the Display MAR key.
One instruction is executed with each depression of the SIE key.
This steps through the eight I cycles.
Initiates manual mode.
The Q address, which is in OR-1, is displayed in MAR.
The P address, which is in OR-2, is displayed in MAR.
Note: If it is desired to continue program operation after Display, the following actions should be taken:
1. Prior to Reset (step 4) the on/off conditions of machine status and check indicators should be noted.
2. After Display (step 6) a Branch back to some instruction in the program should be inserted. This instruction should be one that will go back to where the indicators reset (step 4) will not affect program operation.
If Reset and the subsequent necessity for branching and restart are un-desirable, steps 4-6 can be omitted and the P and Q addresses can be viewed, two digits at a time, during step 3 as they move through MBR to OR-2 and OR-1. (See Program Testing section.)
Thorough documentation and preparation should pre-cede the testing of all programs. Careful console oper-ation is next in importance. The following console operating procedures are helpful in analyzing pro-grams in the computer.
