Normally memory locations are accessed by a *memory mapped* name, such as ``cbm.BGCOL0`` that is defined

@ -145,20 +145,16 @@ Normally, the system's default IRQ handling is not interfered with.
You can however install your own IRQ handler (for clean separation, it is advised to define it inside its own block).
There are a few library routines available to make setting up C64 60hz IRQs and Raster IRQs a lot easier (no assembly code required).
For the C64 these routines are::
These routines are::
c64.set_irq(uword handler_address, boolean useKernal)
c64.set_rasterirq(uword handler_address, uword rasterline, boolean useKernal)
c64.restore_irq() ; set everything back to the systems default irq handler
sys.set_irq(uword handler_address, boolean useKernal)
sys.set_rasterirq(uword handler_address, uword rasterline, boolean useKernal)
sys.restore_irq() ; set everything back to the systems default irq handler
And for the Commander X16::
Note that for the CommanderX16 the "useKernal" parameter doesn't exists for the set_rasterirq() routine;
it will always disable the system IRQ handler (which also means the default sys.wait() routine won't work anymore)
cx16.set_irq(uword handler_address, boolean useKernal) ; vsync irq
cx16.set_rasterirq(uword handler_address, uword rasterline) ; note: disables Kernal irq handler! sys.wait() won't work anymore
cx16.restore_irq() ; set everything back to the systems default irq handler
The Commander X16 syslib does provides two additional routines that should be used *in your IRQ handler routine* if it uses the Vera registers.
The Commander X16 syslib provides two additional routines that should be used *in your IRQ handler routine* if it uses the Vera registers.
They take care of saving and restoring the Vera state of the interrupted main program, otherwise the IRQ handler's manipulation
will corrupt any Vera operations that were going on in the main program. The routines are::

TODO
====
New major release 9.0
^^^^^^^^^^^^^^^^^^^^^^
- renamed builtin function sqrt16 to sqrtw for consistency
For next minor release
^^^^^^^^^^^^^^^^^^^^^^
- try to optimize newexpr a bit more
- once 9.0 is stable, upgrade other programs (assem, shell, etc) to it.
...
For 9.0 major changes
^^^^^^^^^^^^^^^^^^^^^
- copy (not move) the CBM kernal romsubs to a new 'cbm' block so programs on c128 and cx16 can also
simply refer to cbm.CHROUT rather than c64.CHROUT which looks a bit silly on the non-c64 cbm systems.
we keep the old definitions intact because of backwards compatibility reasons.
- try to reintroduce builtin functions max/maxw/min/minw that take 2 args and return the largest/smallest of them.
This is a major change because it will likely break existing code that is now using min and max as variable names.
Also add optimization that changes the word variant to byte variant if the operands are bytes.
