+ Purpose +

This reference manual describes the Erlang programming + language. The focus is on the language itself, not + the implementation. The language constructs are described in + text and with examples rather than formally specified, with + the intention to make the manual more readable. + The manual is not intended as a tutorial.

+

Information about this implementation of Erlang can be found, for + example, in System Principles (starting and stopping, + boot scripts, code loading, error logging, creating target + systems), Efficiency Guide (memory consumption, system + limits) and ERTS User's Guide (crash dumps, drivers).

+
+ +
+ Prerequisites +

It is assumed that the reader has done some programming and + is familiar with concepts such as data types and programming + language syntax.

+
+ +
+ Document Conventions +

In the document, the following terminology is used:

+ + A sequence is one or more items. For example, a + clause body consists of a sequence of expressions. This + means that there must be at least one expression. + A list is any number of items. For example, + an argument list can consist of zero, one or more arguments. + +

If a feature has been added recently, in Erlang 5.0/OTP R7 or + later, this is mentioned in the text.

+
+ +
+ Complete List of BIFs +

For a complete list of BIFs, their arguments and return values, + refer to erlang(3).

+
+ +
+ Reserved Words +

The following are reserved words in Erlang:

+

after and andalso band begin bnot bor bsl bsr bxor case catch + cond div end fun if let not of or orelse query receive rem try + when xor

+
+ +
+ Character Set +

In Erlang 4.8/OTP R5A the syntax of Erlang tokens was extended to + allow the use of the full ISO-8859-1 (Latin-1) character set. This + is noticeable in the following ways:

+ + +

All the Latin-1 printable characters can be used and are + shown without the escape backslash convention.

+ + +

Atoms and variables can use all Latin-1 letters.

+ + + + + Octal + Decimal +   + Class + + + 200 - 237 + 128 - 159 +   + Control characters + + + 240 - 277 + 160 - 191 + - ¿ + Punctuation characters + + + 300 - 326 + 192 - 214 + À - Ö + Uppercase letters + + + 327 + 215 + × + Punctuation character + + + 330 - 336 + 216 - 222 + Ø - Þ + Uppercase letters + + + 337 - 366 + 223 - 246 + ß - ö + Lowercase letters + + + 367 + 247 + ÷ + Punctuation character + + + 370 - 377 + 248 - 255 + ø - ÿ + Lowercase letters + + Character Classes. +
