Yes, there is. In fact, it is quite common to have variables in the
code which are not being use *at this time*. And very good reasons for
*not* initializing them - as a *programmer* would know.

Just because the are not being used *at this time* doesn't mean they
shouldn't appear - as a *programmer* would understand.

Or the row (tables have ROWS, not RECORDS) is not being updated with the
correct data - which is the case here. But then a *programmer* would
understand that.

Typo - the rfc is 3676, which you could find if you knew how to do a
simple google search. But that looks to be beyond your capability, also.

There are three types of people who refuse to follow accepted practices:
idiots, trolls and arrogant anal orifices.

Which are you?
