Here is what I'm doing:



00F9  MYROUTINE:                               ; Start Callable routine
(located at ROM address 0x00F8)
                                     goto TASK          ; Jump to somewhere
outside the first 256 bytes of ROM
00FB TSKRTN:          return                   ; Exit "MYROUTINE"
        :
        :
011E  TASK:                                            ; Start the work for
"MYROUTINE" outside the first 156 bytes of ROM
       :
       :
0129                            goto TSKRTN      ; Done with the work,
return to "MYROUTINE"
