Calling SetResLoad

Calling SetResLoad(FALSE) can be useful if you need to get a handle to a resource, without causing the resource to be loaded from disk if it isn't already in memory. SetResLoad changes the value of the low-memory global ResLoad (at location $A5E).

It is very important that your program not leave ResLoad set to FALSE when it exits. Doing this will cause the system to reboot or crash when it does a GetResource call for the next code segment to be loaded (usually the Finder). The system will crash because GetResource will not actually load the code from disk when ResLoad is FALSE.

So, make sure that you call SetResLoad(TRUE) before exiting your program.
