Standard prelude (The GNU Algol 68 Compiler)

## 6 Standard prelude ¶

The Algol 68 Revised Report defines an extensive set of standard modes, operators, procedures and values, collectively known as the standard prelude.

The standard prelude is available to Algol 68 programs without needing to import any module.

For brevity, in this section the pseudo-mode `L` represents a shortsety, i.e. a sequence of either zero or more `LONG` or zero or more `SHORT`.
