|

|
|
<P>The runtime for the Commodore 610 uses routines marked as <CODE>.CONDES</CODE> type 2
|
|
for interrupt handlers. Such routines must be written as simple machine
|
|
language subroutines and will be called automatically by the interrupt handler
|
|
code when they are linked into a program. See the discussion of the
|
|
<CODE>.CONDES</CODE> feature in the
|
|
<A HREF="ca65.html">assembler manual</A>.</P>
