Answer / mike m
A SINGLE BASE REGISTER ACCOUNTS FOR 4096 BYTES OF STORAGE.
YOU NEED A BASE REG. FOR EACH 4K. IF YOUR PROGRAM IS 12K,
YOU NEED AT LEAST 3 BASE REGS.

Answer / ajay kuriyal
it all depends upon the length of your program , if it is
more than 4095 then we need 2 register else only one can do
needful.
basically we can even use savearea register as a base
register, so as to accomodate the length of the program

Answer / dave grund
The more correct answer would be to address storage. Each register can address (or make reference to) 4,096 bytes of contiguous storage. If you need to address more storage than that, you need to initialize and use additional base registers.
