Sounds like a useful hack, since it is quite rare that one used
different values. Can you send me the hacked readir.c code?
A general problem with automating stuff is that people may stop
thinking... Let's be honest if you want to get something done and get a
messagebox with the options Cancel OK, then you click OK (I do...).
However for scientific programs the user should know what (s)he's doing...

It's just that, they won't fit on the screen otherwise.
If you have more hacks that you think are of general interest please
send them to me.
