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.
