#99968 - I am sorry
Responding to: ???'s previous message
Russell,

please don't take my comments personally. I just wanted to point out to Jeroen a couple of things - and your short example just came handy... I am sorry, if it offended you, believe me, it was never my intention to do so.
In fact, you and others are probably absolutely right - it is the best practice to save/restore psw and acc and avoid using registers (while not changing register banks - but that's another nontrivial issue) in interrupt service routines.

One might this call an example of aggressive versus defensive coding, isn't it?
