I have two questions.<br><br>1) How do you write data out to a file in text format? I know there is an fwrite command, but I don't really know how it works.<br><br>2) Can the cdiff command work when three environment dimensions are varying? I'm trying to compute EPV, but to do so, I need to do a cdiff command in the x, y, and z dimensions, but I always get an error and usually Grads crashes when I do it.<br>
