****  A tool to grab succesive screen grabs from Digital Universe which can be
compiled into an animation *****

      Requires:

		Reqtools.library and rexxreqtools.library to be installed to work. I may find
another way of
       		doing requesters later. Sgrab requires easyrexx.library to use its
Arexx port.

                SGrab to grab the DU screen images.

                Obviously you will also need Digital Universe version 1.5 or
version 1.6.

                It will NOT work with 68k versions of Digital Universe (1.03 and
below) as they have no Arexx interface.

       Usage.
       		First run Digital Universe and set up your desired screenmode and the
start time and the advance
                step time, and also the object or postion you want to lock onto.
Set whatever display mode
                requirements you want, which will probably vary depending upon
the animation you want to do. Likewise
                choose an appropriate Local or Planetarium mode.

                Then start Sgrab.

                Run this script, it has an icon with the default tool "rx" so
you can do it from the WB.

                The script will warn and exit if the above applications are not
ready.

                Select the directory and filename to store the images in using
the script's file requester.
                Leave in the {number} part or you will simply overwrite the same
filename. {number} tells
                SGrab to insert numbers starting at 000 and incrementing each
grab.

                Then enter the number of images you want to grab. This has to be
between 1 and 999.

                Then sit back and wait.

                If you want to add more images run the script again, use the
same basename for the file and the {number}
                increment to add more frames from the point you left off - as
long as you have not messed around with DU
                in the interim !
