2.3.10 Char-Table Type

A char-table is a one-dimensional array of elements of any type, indexed by character codes. Char-tables have certain extra features to make them more useful for many jobs that involve assigning information to character codes--for example, a char-table can have a parent to inherit from, a default value, and a small number of extra slots to use for special purposes. A char-table can also specify a single value for a whole character set.

The printed representation of a char-table is like a vector except that there is an extra `#^' at the beginning.

See section 6.6 Char-Tables, for special functions to operate on char-tables. Uses of char-tables include:

• Case tables (see section 4.9 The Case Table).

• Character category tables (see section 35.9 Categories).

• Display tables (see section 38.17 Display Tables).

• Syntax tables (see section 35. Syntax Tables).
