====case expressions====
Using the same example above, we assume that the <syntaxhighlight lang="ada">''Operation</syntaxhighlight>'', <syntaxhighlight lang="ada">''Op</syntaxhighlight>'', and <syntaxhighlight lang="ada">''Result</syntaxhighlight>'' variables are declared. A case expression over the enumeration of operations might look like:
<syntaxhighlight lang="ada">Result := (case Op is
Add => A + B,
Line 597:
</syntaxhighlight>
Note: some websites (particularly [https://www.radford.edu/nokie/classes/320/abe/operators.html#:~:text=if%20and%20case-,Examples%3A,1%2C%20others%20%3D%3E%200)%3B this one]) contain a different variant of a case expression (<syntaxhighlight lang="ada">case Op of...</syntaxhighlight>). The Ada Reference Manual indicates this is incorrect, and we use the [http://www.ada-auth.org/standards/12rm/html/RM-4-5-7.html formal version] here.
 
===case with a default alternative===
<syntaxhighlight lang="ada">type Days is (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday);
