This document provides a complete list of procedures and special forms implemented in version 1.60 of STklos. The language implemented by STklos is nearly compliant with the language described in the Revised⁵ Report on the Algorithmic Language Scheme (aka R⁵RS) [13]. However, since version 1.30, the goal is to make it more compliant with R⁷RS [3]. This document states the compliance of each construction relatively to these reports, or if it is a STklos extension.
