When the program is executed on a computer the type of central processing unit in the computer is identified and a suitable resident part is selected. The selected resident part is then assembled from the code and data contained in the terminate and stay resident program and is installed as the resident part so that it can be made use of subsequently by the operating system present in the computer or by an application program.
