Using the visual development environment interface to launch Array Viewer requires no modifications of a source program. It lets you inspect the array data and optionally save the entire array to an .AGL file for later viewing.
Array Viewer includes many user interface controls that can adjust the way in which data is presented. For example, you can select a particular sub-region of the array to be displayed. See the Array Viewer help (Aviewer.hlp) for more information on how to use Array Viewer.
Using the Fortran or C routines (Aview library) lets the application launch Array Viewer independently of the visual development environment to display array data. The number of function calls needed is quite small and is available to any type of project type (Fortran Console, Fortran QuickWin, Fortran Windows, and so on). The Aview library provides a way to save array data directly to an .AGL file for later viewing with Array Viewer.
Using the Avis2D or AvisGrid controls is slightly more complicated than using the API, and they require a development environment that supports ActiveX controls. You can use these controls to do the following:
