To Use a Program
1.
Turn computer ON.
2.
Touch GENERAL RESET.
3.
Turn RECORD PROGRAM and PRINT PROGRAM switches OFF (out). 4 Set DECIMAL WHEEL
to desired position.
4.
Insert the program card into the computer. The program card can be removed from the
computer at any time, since the program is transferred directly to the memory. If the
program is to be repeated, the program card need not be reinserted since the program
remains in the computer.
5.
Depress the proper ROUTINE SELECTION key.
6.
Operations will occur as explained in the operating procedure. The keyboard will lock
during computations. When variable factors are to be entered, the program will stop and
the keyboard will be unlocked to permit data entry.
Automatic Internal Checks
Programma 101 provides a system of automatic internal checks to assure the operator that all
components are functioning properly. The red ERROR light is the visual indication that a mis-
operation has been detected.
When a magnetic program card is misread, the error indicated is usually either the result of a
damaged or dirty card, or the improper insertion of the card.
examine the physical condition of the card and if there is
no evidence of damage, reinsert the card properly.
The following mis-operations are indicated by the
Error light
:
•
Capacity exceeded by computation. The original contents of registers A and R are
destroyed.
•
Capacity of a split register exceeded by a transfer. The transfer is not performed.
•
Division by zero.
•
Keyboard entry capacity exceeded. To repeat the entry correctly, the clear entry key must
first be depressed.
•
An erroneous attempt has been made to store data and instructions in the same register.
(See discussion of storage of data and instructions in the same register).
the following steps provide the information basic to the analysis of the above errors:
•
print out all registers
•
print out program from point of error (the instruction immediately preceding the first
printed instruction is the operation that caused the error)
•
print out the complete program
