<sect1>Interrupts<p>
The runtime for the VIC20 uses routines marked as <tt/.CONDES/ 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 <tt/.CONDES/
feature in the <htmlurl url="ca65.html" name="assembler manual">.
