The Revised(4) Report on the Algorithmic Language Scheme (R4RS) was released more than 30 years ago, on November 2nd, 1991. Inlab Scheme formally complies to this language definition. You will find any Inlab Scheme specific notes in a blue “Note” box like this. To explore the various extensions that Inlab Scheme provides (including all concepts and influences from higher revised reports), have a look at the Data Types and Expressions and Procedures sections of this online reference manual.
