A Method of Data Processing in Fortran，es pecially under the FACOM 270-20 Computing System

摘要

In this pepar，we report a processing method on some kind of data in Fortranprogrammmg.Usually，when we treat numerical data in our program，a memory unit ofcomputer is used by the word. In case of the FACOM 270-20，it's composedof 16 bits.Therefore，in any way，we cannot treat a piece of bit divided from the word.But there are many of opportunity that we want to divide the word into two ormore part，and use these.For instance，when we have to treat ac omputer simulation or al ist processing，such a problem often requires us a method of treatment of bit-like data.However，with the lack of bit data handling we can do nothing about our sucha problem.Under these circumstances，we tried to treat bit-like data by use of as ubroutinesubprogram，which is coded by an assembler language，FASP.
