Two more:

Ada is a name, not an abbreviation. It should be written "Ada" and not "ADA".

Keywords in Ada should be written in lower case letters:

It is a common misconceptions that Ada enforces or encourages upper case, but here is the official Ada 83 Language Reference Manual on the subject: http://archive.adaic.com/standards/83lrm/html/lrm-02-09.html... > Reserved words differing only in the use of corresponding upper and lower case letters are considered as the same (see 2.3).

The manual itself doesn't even use upper case:

> For readability of this manual, the reserved words appear in lower case boldface.

So even the Ada standard recognizes the upper case is less readable and undesired.
