Well \makeatletter makes @ (at) to a letter, which means that you
can use commands with @ in their names (command names end at the
first non-letter char), \makeatother makes @ to a "non-letter".
Thanks for your clear explanation, Ulrike.
But naming commands with @ is only a convention, isn't it?
Yes, but it is more than just this.
It means that a macro's meaning cannot be accidentally redefined,
without first going to the trouble of changing the status
of the @ character.
Only someone who knows (pretty much) what they are doing
will have tried that, so it serves as a safety mechanism too.
Thanks again,
Pablo
Hope this helps,
Ross
