Language summary keywords

[edit | edit source]

Most Ada “keywords” have different functions depending on where they are used. A good example is for which controls the representation clause when used within a declaration part and controls a loop when used within an implementation.

In Ada, a keyword is a reserved word, so it cannot be used as an identifier. Some of them are used as attribute names.
