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. #### 13.1.9.2: 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. #### 13.1.9.3: 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. #### 13.1.9.4: 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. #### 13.1.9.5: 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.
