Re: A83: Re: Ion 1.4 vs Ion 1.6


Ion 1.5/1.6 should allow you to do the second (access programs regardless of
order) but not the first (GetKey stuff).  MirageOS will allow you to do
both.  If you want to trap 2nd+Off under GetKey you just have to make a call
to the library interrupt setup routine (details are in the MirageOS dev
docs).  Of course it's possible to setup an interrupt routine in your Ion
program so to stop GetKey from doing bad things...the difference is that
such a routine is built into MirageOS, but not Ion.
