As with the section on symbolic logic, a few gluttons for punishment among my colleagues asked for this.
Ok, one day my boss asked “what’s all this I hear about Scheme continuations,” (more or less) and the discussion eventually evolved into this.
Examples demonstrating various Scheme features and built-in procedures including:
call-with-current-continuation -- a.k.a.call/cc`
They provide simple, if somewhat contrived, samples of idioms commonly used in Scheme_ programming.
\note These examples were created and debugged using the Guile – http://www.gnu.org/software/guile/ – dialect, but should work as-is in most variants of Scheme.
