Abstract

An improved method of transferring data among computer system Input/Output devices (10, 12) by an application running under a nonpreemptive multitasking operating system. Data is transferred in blocks between Input/Output devices (10, 12) wherein the blocks are continually and dynamically re-sized during the transfer of the data. The method further includes the step of relinquishing control of the computer system central processing unit between each transfer of a data block whereby performance of the computer system is improved. The method achieves relatively uniform response time independent of the speed of operation of the Input/Output devices (10, 12).
