13.1.9: Version 2.4 Version 2.4.4 [2000 May 7]

Change so that only a warning is printed if mathematical operations are requested on empty arrays (e.g. `y += 10'). Previously, an error was reported and Gri exited with an error condition, which is bothersome in scripts that rely on successful completion of the Gri job.

Port to the BeOS operating system. Version 2.4.3 [2000 Apr 1]

Change location of all files, to be consistent with Redhat convention. Previously, things were in `/opt/gri'; now they are in more standard locations. Version 2.4.2 [2000 Mar 25]

Remove bug in which `convert grid to image' produced incorrect images, visible as a patchy appearance with coarse grids. Version 2.4.1 [2000Jan 31]

Remove bug in which `convert image to grid' failed to take note of the gri minimum and maximum, so that contouring of the grid was not possible for grids created from images. Version 2.4.0 [2000 Jan 05]

Add `set input data separator'. Make `read columns' work with various input separators. Make `read .x.', etc, work with various input separators.
