>>I agree in some facets a weight can be put on things (say the difference
between an malfunctioning ATM bank machine vs a malfunctioning pacemaker) but
still, I'd make the effort for both of them.<<
Agreed. What I meant is that, very often, you have an error that will never be
seen during the useable life of the program. When I made the calculation
library for my accounting package, there was a typing error in the division
routine. I found a way around this before I discovered the bug. Therefore,
there was an error in the program and yet, the program behaved correctly.
The error was this:
moveq.l #0,d0
moveq.l #0,d0
it had to be:
moveq.l #0,d0
moveq.l #0,d1
For a reason that still deludes me I only found this error more than a year
after having written the routine when I was looking for something else.
And yes, I also always do the best I can to avoid errors.
