I forget how I found out.  Certainly not in that laughable manual
that comes with the GS/OS package.  Perhaps it was in a ProDOS-16
or GS/OS Reference Manual draft from APDA.  Anyway, what you do is
fire up an icon editor (several are available from information
services now), create an icon file of your own, and in the
auxiliary (i.e. non-graphic) information associated with an icon
specify the information I mentioned above.  The Finder will use
that information to display the appropriate icon (assuming you
put the icon file in the ICONS folder in the root directory of the
disk) and to determine what application to launch when you double-
click on the icon.  Use existing icons as a guide, for example the
ones for the BAS file type (which invoke BASIC.LAUNCHER to handle
the double-clicked BASIC program) located in FINDER.ICONS.
