I have an app info block and now want to change the size (larger)
of the app info structure.  

Can I just redefine the structure (make it larger) and rewrite it 
without worring about the size difference with something like:

    dbID = DmGetAppInfoID(MyDB);   
    appInfoP = MemLocalIDToLockedPtr(dbID, 0); 
    DmWrite(appInfoP, 0, &appInfoStruct, sizeof(MyAppInfoType));
    MemPtrUnlock(appInfoP);

Does this automatically adjust size?  I know I can just try it
but I don't want to wipe out anything.

Mike
