HELP Information on Running SolarSoft under Windows This page assumes that you have already created a SolarSoft installation on your Windows PC using the form in the SolarSoft web pages - see the URL: http://www.lmsal.com/solarsoft/ssw_install_howto.html Although we have attempted to make things as similar as possible, there are several differences in between running SolarSoft under Unix and Windows. These relate mainly to when and where IDL is configured to a particular selection of SolarSoft instruments. Under Unix, most things are done before, or as you enter IDL - under Windows, everything is done within IDL. All the files that define the environment variables under Unix should work. However, when you enter SSW IDL under Windows you will only have the general part of the SolarSoft tree selected (unless you have selected particular set of instrument in sswidl.bat). You then need to select the instruments you wish to use with setssw_windows. Starting SSW: SSW should be invoked by executing the sswidl.bat file that is supplied as part of your SolarSoft installation under Windows. You can do this by double clicking on the sswidl.bat file - you can create a shortcut to this file if you want to. The sswidl.bat file defines a number of things needed to run SolarSoft, including specifying the environment variable IDL_STARTUP. Within IDL, you should clear the preferred startup field - the routine defined by IDL_STARTUP will then be used. IDL_STARTUP should point to IDL_STARTUP_WINDOWS - other SSW initialization is done within ssw_setup_windows which is called by IDL_STARTUP_WINDOWS. None of these routines should need modifying - any adjustments to the location of SSW and SSWDB should be made in the sswidl.bat file.
