Just pass an allocated memory pointer:
Ptr data = MemPtrNew(100); // use the size you need
// fill in data with whatever info you want
SysUIAppSwitch(cardNo, dbID, launchCmd, data);
The system will automatically set the owner ID of data to 0 (so that it
isn't deallocated when application 1 quits). I assume it will deallocate
the data when application 2 quits.
