This publication describes Fortran input/output (I/O) techniques for use on UNICOS and UNICOS/mk systems. It also contains information about advanced I/O topics such as asynchronous queued I/O and logical record I/O. Information about the interaction of the I/O library and the CF90 compiler is also discussed.

This document also serves as an I/O optimization guide for Fortran programmers. It describes the types of I/O that are available, including insight into the efficiencies and inefficiencies of each, the ways to speed up various forms of I/O, and the tools used to extract statistics from the execution of a Fortran program.
