SystemReset limitations?

[Jeff Valore]

Can someone please explain what the limitations are for a program running
after a reset (responding to a SystemReset launch code).  I know there are
no global variables available, but my program doesn't reference any, and it
still dies on a reset.  It runs fine on normal launch, and it does the exact
same lines of code.

Here is the basic outline of the code:

DWord PilotMain( Word launchCode, Ptr cmdPBP, Word launchFlags)
{
        if(launchCode == Normal or SysReset)
        {
                char *dbNames[] = {/*bunch of strings*/};
                LocalID DbLocalID;
                VoidHand dbImageHandle;
                int currDB;
                void *DBImgPtr;

                // these functions are called in this order
                //      (code inbetween calls is left out...
                //      most is variable assignments + if statements)
                DmFindDatabase();
                DmGetResource();
                DmGetResource();
                DmCreateDatabaseFromImage();
                MemHandleUnlock();
                DmReleaseResource();
        }
}

Hope someone out there can tell me what here I can't do!
Thanks!
