ABSTRACT

This package contains the single function "is_Ada_reserved_word". It returns with either a "true" or "false" to the statement "the input character string is a reserved word in the Ada language".

The contribution of the function is that it executes very quickly, being an implementation of the algorithm defined by David Wolverton in "A Perfect Hash Function for Ada Reserved Words", as published in Ada Letter, July-August 1984. It is much faster than either linear or binary searches of all the Ada reserved words.

A test driver is included, as is sample test data.
