4.3 Modifying Format Tables

Customizing the contents of your format tables involves a single function: set-format-directive.

Function: set-format-directive CHAR &key STANDARD FUNCTION (BOTH-CASE t) FORCE (TABLE *format-table*)

Set a ~CHAR directive in TABLE.

TABLE is the format table to modify. It defaults to the current format table, and may otherwise be specified by passing a table designator as value to the :table keyword argument.
