<h3>Standards</h3>
|
||
|
|
|
||
|
|
<p> There are two standards for Scheme: an official standard with IEEE
|
||
|
|
and a de facto one, often called
|
||
|
|
“R<sup><small>n</small></sup>RS”, short for the
|
||
|
|
<cite>Revised<sup><small>n<sup><small>th</small></sup></small></sup>
|
||
|
|
Report on the Algorithmic Language Scheme</cite>. In colloquial use,
|
||
|
|
“Scheme standard” usually refers to the latter. </p>

<p> The IEEE standard, 1178-1990 (R1995), should be available at
|
||
|
|
technical bookstores, and <a
|
||
|
|
href="https://standards.ieee.org/standard/1178-1990.html">
|
||
|
|
from IEEE</a>. I do not believe there are free on-line
|
||
|
|
copies available. According to the document,
|
||
|
|
<blockquote>
|
||
|
|
IEEE publications are available from the Institute of Electrical and
|
||
|
|
Electronics Engineers, Service Center, 445 Hoes Lane, P.O.Box 1331,

Piscataway, NJ 08833-1331, USA.

<p>You can find <a href="https://small.r7rs.org/">R7RS</a> online,

as well as <a href="http://www.r6rs.org/">R6RS</a>.

The <a href="Charter/">Scheme Language Charter</a> documents the

process that led to the creation of R6RS.
