         I have a simple(hopefully)  question  to  ask.   I  am  writing  a
    multipart machine language program for the C128.  I am  trying  to  use
    the indirect bank routines as well as execute  code  in  bank  1.   The
    Programmers Reference Guide states:


         "When  calling  a  non-system  bank,  the  user  should  take
         neccessary precautions to ensure that interrupts  (IRQ's  and
         NMI's) will be handled properly  (or  disabled  beforehand)."

                                                           ...page 453


         Does anyone out there know how  to  hold  off  the  interrupts  or
    disable them while executing code in a non-system bank?  I have  combed
    the manual but after several days of trying I have given up.  Any  help
    would be appreciated.  Thanks.



                                              Sincerely,

                                            Scott Nickerson
