Postscript Output

The user may get hardcopy output in Postscript format from allsky This Postscript output will contain all the information normally appearing on the screen, plus additional information. A description of how to obtain allsky Postscript output is given below.

The `F10' key activates the Postscript printing/hardcopy mode. Once the key is pressed allsky will stay in Postscript mode until it is pressed again. The user is asked for a filename with a default filename provided in square brackets. If the name chosen by the user corresponds to an already existing file, allsky queries the user about whether or not to overwrite the already existing file. If the file is not to be overwritten, a file extension number will be added automatically to the file name, starting with `0'. If the user chooses to create a second plot, the F10 key must be toggled off and then on again. If this is not done, allsky will automatically overwrite the contents of the file previously created. It is possible to increment the filename up to 999, which is the maximum increment possible under DOS filename extension rule.

If Postscript mode is selected, bf allsky will still create a screen plot, but will create the Postscript output immediately after the screen plot has finished. If the user hits the Escape key while allsky is running in Postscript mode, the program will stop immediately and place the program into the initial start mode again. The plot will use all currently specified parameters and cannot be programmed to produce plots which differ from the screen plot. This is meant to help ensure that the user doesn't waste time previewing or printing plots that are not needed.
