18.1 Revised7 Report on the Algorithmic Language Scheme

Description

The core standard for the Scheme language.

https://small.r7rs.org/attachment/r7rs.pdf

Support

Fully supported, with exceptions:

  • Multiple values aren’t supported correctly. Instead values returns a special record containing the values, and call-with-values takes that record apart and passes the values to the receiver. For many uses of multiple values this is adequate.
Libraries

(scheme base) (scheme case-lambda) (scheme char) (scheme complex)
(scheme cxr) (scheme eval) (scheme file) (scheme inexact)
(scheme lazy) (scheme load) (scheme process-context) (scheme r5rs)
(scheme read) (scheme repl) (scheme time) (scheme write)

Global

All names are bound in the MIT/GNU Scheme global environment.
