How do you do the equivalent of a WRITE statement without appending a newline? I want to do several disjoint WRITE's that output onto the same line. Thanks very much for your help! Cordially, Steven G. Johnson. The only major new input/output features in Fortran 90 are NAMELIST, non-advancing I/O and some new edit descriptors..

There are occasions where it would be convenient to read/write only part of a record, and read/write the rest later. Mar 05,  · Non-Advancing IO; Namelist; Manipulating Scientific Data Format Files (netCDF for instance) Prerequisites: Familiarity with any compiled language. Modern Fortran ( days) This tutorial introduces some of the Fortran features. It is meant for practioners who are familiar with Fortran and want to lear how to do Object Oriented Programming. A non-advancing read will still set the file position to before start of the next record if the end of the current record is encountered while reading from the file to satisfy the items in the output item list of the read statement - non-advancing doesn't mean "never-advancing".
