Hi Noel,
I wasn't familiar with the term ‘condition handler’. That page starts
‘A condition handler (sometimes exception handler) refers to a
mechanism in some programming languages which allows the programmer
to provide code to handle the occurrence of a exception or condition
(terminology varies, but the substance does not).’
Oh, exceptions. I know what they are and if you say above that most
people are unfamiliar with them due to their use of goto then that's
probably wrong.
There are good reasons languages like Go chose not to include them.

Cheers, Ralph.
In C I use it
all the time to do goto err for common error recovery
because C doesn't have anything better.
That's because C doesn't have 'conditions'. (Apparently, from the
following
posts, most people here are unfamiliar with them. Too bad, they are a great
idea. OK summary here:
