The left curly bracket { is defined in ASCII as having the value is 123 (hexadecimal $7B).
In Pascal it always appears in conjunction with a corresponding right curly bracket constituting a pair.
Such a pair is used to:
- write block comments
- FPC and Delphi interpret such comments with an initial dollar sign as compiler directives, for example
{$longStrings on} - integrated development environments such as Lazarus interpret block comments with an initial percent sign as IDE directives, for instance
{%H-}

| character pairs |
