On the current DiskTop release disk, there is now a dedicated application
called "Heap Fixer" that can be used to change the System Heap size.  The
supplied directions are less than clear, however; you have to experiment with
it.  If you have a copy of Fedit, you may be able to use that instead.  Fedit
allows editing of the boot blocks on a startup disk, and the System Heap size
is stored there.  Since Fedit has not been updated in (??) years, I am not
sure whether the current boot blocks structure is consistent with its block
editor.  Does anyone know for sure?
