|VECTOR||FF8D||Manage RAM Vectors|
This routine manages all system vector jump addresses stored in RAM.
Calling this routine with the the accumulator carry bit set stores the current contents of the RAM vectors in a list pointed to by the X and Y registers.
When this routine is called with the carry clear, the user list pointed to by the X and Y registers is transferred to the system RAM vectors.
The RAM vectors are listed in the memory map.
