I just wanted to add something to Byron's posting:

If you want to grow the System Heap by a fixed ammount whevever your INIT is
installed, then you can include a sysz resource in your INIT file.  The
sysz resource has a longword of data which is the number of bytes your INIT
needs added to the size of the system heap.

Under MultiFinder the system heap grows dynamicly.  Without MultiFinder the
best you can do is change the value of the sysz resource and reboot.  This
can be useful when you are, for example, keeping a desktop picture in RAM:
When the user chooses a new picture, which has a different size, you can
allocate a different ammount of memory.
