From 1997 to 2007, Ada Magica was my column in Softwaretechnik-Trends, the periodical of Ada Germany, the special interest group 2.1.5 Ada of the German Informatics Society (GI). It was dedicated to Ada's not so well-known sides. Since this is a German group, articles appeared in German.
This is a list of articles that appeared in the Softwaretechnik-Trends (SWTT), which I translated into English.
This is essentially an Ada83 specific problem, but since the old standard is still heavily in use and also some basic coding styles are discussed (that are valuable for Ada95 as well), I deem this problem worth publishing.

The date of first standardization and the standard's number are no coincidence.
