- Abstract
- This report describes the characteristic differences in word formats of two different computers, and the software interface technique for conversion from one to the other. Magnetic tapes produced from a small-scale computer were used as inputs to a large-scale computer. One interface program was developed forSingle-precision floating point numbers. Another interface program was modified from an existing program for alphanumerics. The program for reading real numbers is used as a subroutine in the main program for calculations. The program for reading an alphanumeric coded tape is used by itself to write an ASCII coded file. By using these programs, large-scale computers are able to read and accept data from small-scale computers.
