Powers Of 2 is a demonstration program run on the IBM 1401 computer.

The IBM 1401 stores one digit per memory location.
The IBM 1401 has 16,000 locations of memory.
With this amount of memory, the IBM 1401 can add together two 8,000 digit numbers.!

Modern computers perform integer arithmetic using binary values.
For the IBM PC, the largest value is 64 bits. 
The largest value that can be expressed in 64 bits is  18,446,744,073,709,551,616.
That is 20 digits long.

The Powers Of Two program demonstrates the ability of the IBM 1401 to handle large numbers by starting with a single digit of 2 and then double it until it fills a single print line on the IBM 1403 printer.

In addition of that, the program prints out how you pronounce the resultant number.

The program will terminate with a halt.
If you want to run it again, set sense switch G on, and press start.

If you don’t want to run it again, leave sense switch G off and when you press start, it will look for and read in the next program.
