This documents is designed to allow the Fortran programmer to manipulate ASTERIX data files from within their own code. The example covered here, though basic, can be easily adapted to perform a variety of useful operations.
The first document is a basic introduction to the concepts of ASTERIX programming. It explains in detail how to construct a simple ASTERIX application; using as an example a program that reads in a dataset, modifies its values in some mathematical way and then updates the original file.
It also covers such topics such as program structure, compilation, linking and execution which are common to all ASTERIX applications. The next document will provide a more comprehensive tutorial on the reading and writing of various data types, axes, errors, quality and other basic information.
